+#  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.

+The main mode of decoding is a pre-order travesal of the tree of leaves (numbers, strings...)
+formed by intermediate nodes (arrays and maps).  The cursor for the traversal
+ is the byte offset in the encoded input and a leaf counter for definite
+ length maps and arrays. Indefinite length maps and arrays are handled
+ by look ahead for the break.
+
+ The view presented to the caller has tags, labels and the chunks of
+ indefinite length strings aggregated into one decorated data item.
+
+The caller understands the nesting level in pre-order traversal by
+ the fact that a data item that is a map or array is presented to
+ the caller when it is first encountered in the pre-order traversal and that all data items are presented with its nesting level
+ and the nesting level of the next item.
+
+ The caller traverse maps and arrays in a special mode that often more convenient
+ that tracking by nesting level. When an array or map is expected or encountered
+ the EnterMap or EnteryArray can be called.
+
+ When entering a map or array like this, the cursor points to the first
+ item in the map or array. When exiting, it points to the item after
+ the map or array, regardless of whether the items in the map or array were
+ all traversed.
+
+ When in a map or array, the cursor functions as normal, but traversal
+ cannot go past the end of the map or array that was entered. If this
+ is attempted the QCBOR_ERR_NO_MORE_ITEMS error is returned. To
+ go past the end of the map or array ExitMap() or ExitArray() must
+ be called. It can be called any time regardless of the position
+ of the cursor.
+
+ When a map is entered, a special function allows fetching data items
+ by label. This call will traversal the whole map looking for the
+ labeled item. The whole map is traversed so as to detect duplicates.
