+/**
+ * Client facing API. Parameters are according to the DPE spec version r0.9
+ *
+ * \brief Performs the DICE computation to derive a new context and optionally
+ *        creates an intermediate certificate. Software component measurement
+ *        must be provided in dice_inputs.
+ *
+ * \param[in]  context_handle              Input context handle for the DPE
+ *                                         context.
+ * \param[in]  retain_parent_context       Flag to indicate whether to retain the
+ *                                         parent context. True only if a client
+ *                                         will call further DPE commands on the
+ *                                         same context.
+ * \param[in]  allow_new_context_to_derive Flag to indicate whether derived context
+ *                                         can derive further. True only if the
+ *                                         new context will load further components.
+ * \param[in]  create_certificate          Flag to indicate whether to create an
+ *                                         intermediate certificate. True only if
+ *                                         it is the last component in the layer.
+ * \param[in]  dice_inputs                 DICE input values.
+ * \param[in]  target_locality             Identifies the locality to which the
+ *                                         derived context will be bound. Could be
+ *                                         MHU id.
+ * \param[in]  return_certificate          Indicates whether to return the generated
+ *                                         certificate when create_certificate is true.
+ * \param[in]  allow_new_context_to_export Indicates whether the DPE permits export of
+ *                                         the CDI from the newly derived context.
+ * \param[in]  export_cdi                  Indicates whether to export derived CDI.
+ * \param[out] new_context_handle          New handle for the derived context.
+ * \param[out] new_parent_context_handle   New handle for the parent context.
+ * \param[out] new_certificate_buf         If create_certificate and return_certificate
+ *                                         are both true, this argument holds the new
+ *                                         certificate generated for the new context
+ * \param[in]  new_certificate_buf_size    Size of the allocated buffer for
+ *                                         new certificate.
+ * \param[out] new_certificate_actual_size Actual size of the new certificate.
+ * \param[out] exported_cdi_buf            If export_cdi is true, this is the
+ *                                         exported CDI value.
+ * \param[in]  exported_cdi_buf_size       Size of the allocated buffer for
+ *                                         exported cdi.
+ * \param[out] exported_cdi_actual_size    Actual size of the exported cdi.
+ *
+ * \return Returns error code of type dpe_error_t
