The ICCTAG structure is used to save a tag's information.

A value that indicates the address of the beginning of the tag data element, with respect to the beginning of the profile data stream (which has an address of zero).


A value that indicates the tag data element size in bytes. This value does not include any padded bytes at the end of the data.
