This object is used to specify a Xerox standard or experiemental
message string label associated with the current value of the
message string pointed to by 'xcmGenMessageMapStringIndexOID'.
Usage: Experimental message string labels SHOULD NOT be used in
shipping versions of Xerox-branded products or services. They
exist solely to facilitate rapid product development cycles.
Usage: All Xerox message string label values SHALL
be specified using display (NOT space) characters from the IANA
registered charset 'utf-8' (ie, the UTF-8 octet-stream encoding
of ISO-10646 UCS-4, described in RFC 2279).
Usage: All Xerox message string label values SHALL
contain no more than 64 UTF-8 display characters AND no more
than 128 total octets (in some scripts, less than 64 characters
in UTF-8 octet-stream encoding).
Note: New or refined message label syntaxes MAY be defined in
future versions of the XCMI General TC.
