RE: [Ltru] Re: #944 in draft -04



Hi,

The charset name limit of 40 is _only_ for the "cs..." Alias
required for the MIBenum (numeric) value for the IANA Charset
MIB.  

Here's the relevant quote from page 4 of RFC 2978:

   "All charsets MUST be assigned a name that provides a display string
   for the associated "MIBenum" value defined below.  These "MIBenum"
   values are defined by and used in the Printer MIB [RFC-1759].  Such
   names MUST begin with the letters "cs" and MUST contain no more than
   40 characters (including the "cs" prefix) chosen from from the
   printable subset of US-ASCII."

The limit in the registry itself of all charset names to 40 characters
has been there for years as a comment, so I suppose that's the rule that 
IANA _thinks_ they're enforcing (despite Frank's examples).


Cheers,
- Ira
