RE: Words for charset

[ian.c.jones@bt.com]

Chris, etc.,

	I think your alternative is ok. I have always been concerned about
exactly which word to use to describe the relationship between the 2.  I
choose "compatible" thinking that in some case someone might want the XML
encoding to be a subset of the charset e.g. charset UTF-16, XML encoding
UTF-8. You suggest "consistent".  I think we have the same "meaning
requirement" but finding the "best/right" word is always difficult when
defining a concept without going to a very long and precise definition that
no one every reads or understands!

	While typing this I realized this : MUST the XML encoding be a
subset of the charset - Dick? (Yes it may be a complete 1 to 1 subset.)
What happens if some one uses the UTF-16 encoding for the XML and an
ISO-???? for the charset?

	As to your question about not identical - can you always tell the
"MIME" encoding S/W which charset to use ?  If the S/W decides then that may
the case you are looking for.

Ian,

Pretty good. A couple of suggested changes:

The charset attribute SHALL be consistent with the encoding attribute of the
ebXML message Header XML Document (described in section 3). It is strongly
RECOMMENDED that they are identical. For maximum interoperability
it is RECOMMENDED that UTF-8 be used.  Note: this is not the default for
MIME


NB, I am trying to think of a case where the encoding/charset would
NOT be identical, in which case the second sentence could be omitted.

Cheers,

Chris
