+## Spiffy Decode
+
+In mid-2020 a large addition makes the decoder more powerful and easy
+to use. Backwards compatibility with the previous API is retained as the
+new decoding features layer on top of it.
+
+The first noticable addition are functions to Get particular data types.
+These are an alternative built on top of GetNext that does the type
+checking and in some cases sophisticated type conversion. They
+track an error state internally so the caller doesn't need. They also
+handle the CBOR tagged data types thoroughly and properly.
+
+In line with all the new Get functions for non-aggregate types
+there are new Enter functions for aggregate types. When
+an array or map is expected, Enter is called to descend
+into them. When a map is Entered it can be searched
+by label. Duplicate detection of map items is performed.
+
+An outcome of all this is that now the decoding implementation of
+some data can look very similar to the encoding of some data
+and is generally easier to implement.
+
+ Example...
+
+The handling of byte-string wrapped CBOR like the COSE payload
+and tag 24 is improved.
+
+If decoding of more than one protocol is
+implemented then more of the CBOR-related code is reused.
+For example map searching and duplicate detection is reused.
+This may reduce object code size.

+# Types and Tagging in CBOR
+
+## New Types
+
+CBOR provides a means for defining new data types that are either
+aggregates of the primitive types or the association of further sematics
+to a primitive type.
+
+An aggregate is similar to a C structure. A bigfloat is an example. It
+is an array of two data items, an exponent and a mantissa.
+
+An example of association of further semantics to a primitive type
+is an epoch date, where the new data type is
+a primitive integer that is to be interpreted as a date.
+
+## Explicit Tags
+
+These new types can be explicitly tagged by preceding them
+with a CBOR Item of major type 6. The tag data item is a positive
+integer.
+
+For example the epoch date looks lie this:
+
+
+A big float looks like this:
+
+
+The data item tagged is known as the tag content. Most tags
+require the content to be of a specific type or types. A few work
+with content of any type.
+
+There may be more than one explicit tag for a single tag content. When
+this is done, they nest. The order of the explicit tags is significant. The explicit
+tag closes to the content is applied first. That then becomes the
+content for the next closest tag.
+
+If the content for a specific tag is not of the right type then
+the encoded CBOR is invalid.
+
+The explicit tag data item is not always required when the data type is used. In some situations
+in some CBOR protocols, they may actually be prohibited.
+
+## Standard Tags and the Tags Registry
+
+Tags used in CBOR protocols should at least be registered in
+the IANA CBOR Tags Registry. A small number of tags (0-23),
+are full IETF standards. Further, tags 24-255 require published
+documentation, but are not full IETF standards. Beyond
+tag 255, the tags are first come first served.
+
+There is no range for private use, so any tag used in a
+CBOR protocol should be registered. The range of tag
+values is very large to accommodate this.
+
+It is common to use data types from the registry in a CBOR protocol
+without the explicit tag, so in a way the registry is a registry
+of data types.
+
+## When Explicit Tags are Required
+
+In many CBOR protocols, the new type of a data item
+can be known implicitly without any explicit type. In that
+case the explicit tag is redundant. For example,
+if a data item in a map is labled the "expiration date",
+it can be inferred that the type is a date.
+
+All CBOR protocols that use registered data types
+should explicitly say for each occurance whether
+the explicit tag is required or not. If they say it is required,
+it must always be present and it is a protocol decoding
+error if not. Usually the tag is explicitly required because
+it is not possible to infer the type from the context
+of the protocol.
+
+If the protocol says the explicit tag is not required, it
+is a decoding error if it is present.
+
+That is tags are not optional in a protocol (even though they
+were called "optional tags" in RFC 7049).
+
+Part of the result of this is that unknown tags generally
+can't be ignored during decoding. They are not like
+email or HTTP headers.
+
+The QCBOR encoding API for standard registered types
+has an option to include the tag or not. Setting this
+flag depends on the protocol definition and should only
+be true if the protocol requires explicit tagging.
+
+The QCBOR decoding APIs for standard registered types
+has a tag requirements flag. If true it requires the tag
+to be present and sets an error if it is absent. If false
+an error is set if it is present.
+
+During decoding, it will sometimes be necessary to
+peek-decode the data item with the generic PeekNext()
+first to know its type, then call the appropriate GetXxxx(0
+to actually dcode and consume it. When this is necessary
+depends on the design and flow of the protocol.

- This describes CBOR decoding.
+Q C B O R D e c o d e
+
+ This section just discusses decoding assuming familiarity with the general
+ description of this encoder / decoder in section XXX.
+
+ Encoded CBOR can be viewed to have a tree structure
+ where the lead nodes are non-aggregate types like
+ integers and strings and the intermediate nodes are
+ either arrays or maps. Fundamentally, all decoding
+ is a pre-order traversal of the tree. Calling
+ GetNext() repeatedly will perform this.
+
+ This pre-order traversal gives natural decoding of
+ arrays where the array members are taken
+ in order, but does not give natural decoding of
+ maps where access by label is usually preferred.
+ Using the EnterMap and GetByLabel methods,
+ map items can be accessed by label. EnterMap
+narrows decoding to a particular map. GetByLabel
+ allows decoding the item of a particular label in
+ the particular map. This can be used with nested
+ maps by calling EnterMapByLabel.
+
+ When EnterMap is called, pre-order traversal
+ continues to work. There is a cursor that is run
+ over the tree with calls to GetNext. This can be
+ intermixed with calls to GetByLabel. The pre-order
+ traversal is limited just to the map entered. Attempts
+ to GetNext beyond the end of the map will give
+ the HIT END error.
+
+ There is also EnterArray to decode arrays. It will
+ narrow the traversal to the extent of the array
+ entered.
+
+ GetByLabel supports duplicate label detection
+ and will result in an error if the map has
+ duplicate labels.
+
+ GetByLabel is implemented by performing the
+ pre-order traversal of the map to find the labeled
+ item everytime it is called. It doesn't build up
+ a hash table, a binary search tree or some other
+ efficiently searchable structure internally. For simple
+ trees this is fine and for high-speed CPUs this is
+ fine, but for complex trees on slow CPUs,
+ it may have performance issues (these have
+ not be quantified yet). One way ease this is
+ to use GetItems which allows decoding of
+ a list of items expected in an map in one
+ traveral.
+
+ Like encoding, decoding maintains an
+ internal error state. Once a call to the
+ decoder returns an error, this error state
+ is entered and subsequent decoder calls
+ do nothing. This allows for prettier and cleaner
+ decoding code. The only error check needed
+ is in the Finish call.
+
+ An easy and clean way to use this decoder
+ is to always use EnterMap and EnterArray
+ for each array or map. They will error
+ if the input CBOR is not the expected
+ array or map. Then use GetInt, GetString
+ to get the individual items of of the
+ maps and arrays making use of the
+ internal error tracking provided by this
+ decoder. The only error check needed
+ is the call to Finish.
+
+ In some CBOR protocols, the type of
+ a data item may be variable. Maybe even
+ the type of one data item is dependent
+ on another. In such designs, GetNext has
+ to be used and the internal error checking
+ can't be relied upon.

+
+ Spiffy decode is extra decode features over and above the basic
+ decode features that generally are easier to use, mirror the encoding
+ functions better and can result in smaller code size for larger and
+ more complex CBOR protocols. In particular, spiffy decode
+ facilitates getting the next data item of a specific type, setting an
+ error if it is not of that type. It facilitates explicitly entering
+ and exiting arrays and maps. It facilates fetching items by label
+ from a map including duplicate label detection.
+
+ Encoded CBOR can be viewed to have a tree structure where the leaf
+ nodes are non-aggregate types like integers and strings and the
+ intermediate nodes are either arrays or maps. Fundamentally, all
+ decoding is a pre-order traversal of the tree. Calling QCBORDecode_GetNext()
+ repeatedly will perform this.
+
+ This pre-order traversal gives natural decoding of arrays where the
+ array members are taken in order, but does not give natural decoding
+ of maps where access by label is usually preferred. Using the
+ QCBORDecode_EnterMap() and GetXxxInMapX methods, map items can be
+ accessed by label. QCBORDecode_EnterMap() bounds decoding to a
+ particular map. GetXxxInMap methods allows decoding the item of a
+ particular label in the particular map. This can be used with nested
+ maps by using QCBORDecode_EnterMapFromMapX().
+
+ When QCBORDecode_EnterMap() is called, pre-order traversal continues
+ to work. There is a cursor that is run over the tree with calls to
+ QCBORDecode_GetNext(). This can be intermixed with calls to
+ GetXxxInMapX. The pre-order traversal is limited just to the map
+ entered. Attempts to QCBORDecode_GetNext() beyond the end of the map
+ will give the @ref QCBOR_ERR_NO_MORE_ITEMS error.
+
+ There is also QCBORDecode_EnterArray() to decode arrays. It will narrow the
+ traversal to the extent of the array entered.
+
+ GetXxxInMapX supports duplicate label detection and will result in an
+ error if the map has duplicate labels.
+
+ GetXxxInMap is implemented by performing the pre-order traversal of
+ the map to find the labeled item everytime it is called. It doesn't
+ build up a hash table, a binary search tree or some other efficiently
+ searchable structure internally. For simple trees this is fine and
+ for high-speed CPUs this is fine, but for complex trees on slow CPUs,
+ it may have performance issues (these have not be quantified
+ yet). One way ease this is to use QCBORDecode_GetItemsInMap() which
+ allows decoding of a list of items expected in an map in one
+ traveral.
+
+ @anchor Decode-Errors
+ TODO: internal error for GetNext()?
+
+ Like encoding, decoding maintains an internal error state. Once a call
+ to the decoder returns an error, this error state is entered and
+ subsequent decoder calls do nothing. This allows for prettier and
+ cleaner decoding code. In some cases the only error check that may be
+ necessary is the return code from QCBORDecode_Finish().
+
+ The only error check needed is in the Finish call.
+
+ On error, a decoder internal error state is set. The error can be
+ retrived with QCBORDecode_GetError(). Any further attempts to get
+ specific data types will do nothing so it is safe for code to get
+ many items without checking the error on each one as long as there is
+ an error check before any data is used. The error state is reset
+ only by re initializing the decoder or
+ QCBORDecode_GetErrorAndReset(). QCBORDecode_GetErrorAndReset() is
+ mainly useful after a failure to get an item in a map by label.
+
+ An easy and clean way to use this decoder is to always use EnterMap
+ and EnterArray for each array or map. They will error if the input
+ CBOR is not the expected array or map. Then use GetInt, GetString to
+ get the individual items of of the maps and arrays making use of the
+ internal error tracking provided by this decoder. The only error
+ check needed is the call to Finish.
+
+ In some CBOR protocols, the type of a data item may be
+ variable. Maybe even the type of one data item is dependent on
+ another. In such designs, GetNext has to be used and the internal
+ error checking can't be relied upon.
+
+
+ ----
+ GetNext will always try to get something. The other Get functions
+ will not try if there is an error.
+
+ Make it a decode option for GetNext to not try? That way it is
+ the same as all Get functions and can be used in the mix
+ with them?
+
+ GetNext is how you get things in an array you don't
+ know the type of.
+
+ ----
+
+ @anchor Tag-Matcing
+
+ Data types beyond the basic CBOR types of numbers, strings, maps and
+ arrays can be defined and tagged. The main registry of these new
+ types is in in the IANA registry. These new types may be simple such
+ as indicating an number is actually a date, or they of moderate
+ complexity such as defining a decimal fraction that is an array of
+ several items, or they may be very complex such as format for signing
+ and encryption.
+
+ When these new types occur in a protocol they may be tagged to
+ explicitly identify them or they may not be tagged, with there type
+ being determined implicitly. A common means of implicit tagging is
+ that the type of the value of a map entry is implied by the label of
+ the map entry. For example a data item labeled "birth date" is always
+ to be of type epoch date.
+
+ The decoding functions for these new types takes a tag requirement
+ parameter to say whether the tag must be present, must be absent or
+ whether either is OK.
+
+ If the parameter indicates the tag is required (@ref
+ QCBOR_TAG_REQUIREMENT_MATCH_TAG), then
+ @ref QCBOR_ERR_UNEXPECTED_TYPE
+ is set if a tag with one of the expected values is absent. To decode
+ correctly the contents of the tag must also be of the correct
+ type. For example, to decode an epoch date the tag with value 1 must
+ be resent and the content must be an integer or floating-point value.
+
+ If the parameter indicates no tag is required (@ref
+ QCBOR_TAG_REQUIREMENT_NO_TAG), then
+ @ref QCBOR_ERR_UNEXPECTED_TYPE is
+ set if type of the content is not what is expected. In the example of
+ an epoch date, the data type must be an integer or floating-point
+ value. The tag value of 1 must not be present.
+
+ If the parameter indicated either the tags presence or absence is OK
+ ( @ref QCBOR_TAG_REQUIREMENT_OPTIONAL_TAG ), then the data item(s)
+ will be decoded as long as they are of the correct type whether there
+ is a tag or not. Use of this option is however highly
+ discouraged. It is a violation of the CBOR specification for tags to
+ be optional this way. A CBOR protocol must say whether a tag is
+ always to be present or always to be absent. (A protocol might say
+ that tags are never used or always used in a general statement, or
+ might say it on an item-by-item basis).

+ This is for use on some CBOR that has been wrapped in a

+ wraps a single CBOR data item and 63 a CBOR sequence.
+ This implementation doesn't distinguish between the two
+ (it would be more code and doesn't seem important).
+
+ The @ref Tag-Matcing discussion on the tag requirement applies here
+ just the same as any other tag.
+
+ In other cases, CBOR is wrapped in a byte string, but
+ it is identified as CBOR by other means. The contents
+ of a COSE payload are one example of that. They can
+ be identified by the COSE content type, or they can
+ be identified as CBOR indirectly by the protocol that
+ uses COSE. for example, if a blob of CBOR is identified
+ as a CWT, then the COSE payload is CBOR.
+ To enter into CBOR of this type use the
+ @ref QCBOR_TAG_REQUIREMENT_NO_TAG as the \c uTagRequirement argument.
+
+ Note that byte string wrapped CBOR can also be
+ decoded by getting the byte string with QCBORDecode_GetItem() or
+ QCBORDecode_GetByteString() and feeding it into another
+ instance of QCBORDecode. Doing it with this function
+ has the advantage of using less memory as another
+ instance of QCBORDecode is not necessary.
+
+ When the wrapped CBOR is entered with this function,
+ the pre-order traversal and such are bounded to
+ the wrapped CBOR. QCBORDecode_ExitBstrWrapped()
+ must be called resume processing CBOR outside
+ the wrapped CBOR.
+
+ If @c pBstr is not @c NULL the pointer and length of the wrapped
+ CBOR will be returned. This is usually not needed, but sometimes
+ useful, particularly in the case of verifying signed data like the
+ COSE payload. This is usually the pointer and length of the
