Re: Additional MIME headers

[Matthew MacKenzie <matt@xmlglobal.com>]

Robert,

You make an excellent point.  It really is too bad we weren't defining 
an API.  I think ebXML would get a lot more attention if it did, but 
that's just my opinion.

I think it would be beneficial to at least state in the spec that 
applications _may_ set extra MIME fields, but they will not be used by 
the message server itself for standard ebxml communication.  Having that 
note in there may encourage people to not make changes to the 
ebXMLHeader element for their own purposes, instead using fields in the 
MIME envelope that are harmless to servers/clients that do not 
understand them.

Cheers,

Matt
