C2MS11 — Consider Renaming "Header String" type to "Subject Token String"

I believe the distinction between "Header String" and "String" types is to enforce compliance with Subject Element format (UPPERCASE Alphanumeric, "-" and "_" as only valid values). The description of "Header string" in Table 8-1, Field Type Definitions, indicates that this type is used for "subject name elements".

It's a bit confusing to call this a "Header String", because not all Strings in the Header are Header Strings, and some fields are Header String type even though they are not in the Header (Some examples: USER, SUBCLASS, REFERENCE-ID, and OCCURRENCE-TYPE in Log, CNTL-KEYWORD in Control Message).

In all cases, the fields that are Header String type are intended to be used as subject elements.

One side note, that would need to be fixed, either way is that the actual type listed in Table 8-1, Field Type Definitions, lists the type in two places as "Header string" (lowercase s on string), where everywhere else in the document and in UML model figures, it is listed as "Header String".

do it in 1.1

Make changes in the document to replace "Header String" (or sometimes "Header string") with "Subject Token String". Remove the UPPERCASE limitation everywhere except for the first subject element "C2MS". Increase the suggested length limit from 12 to 25 characters. Make consistent the use of "C2MS Subject Name" and "subject name" capitalization (capitalized as C2MS Subject Name, other wise not capitalized).
