Dear XML Core team:

(This clarification to Dave's note has no official standing as far as the 
protocols WG goes, but I'll offer it for what it's worth...)

>> In summary, it proposes that SOAP 1.2 should 
>> disallow the use of xml:base attributes on 
>> SOAP elements

As most of you are aware, SOAP is a vocabulary for creating envelopes, 
which can be used for structuring XML-based messages.  The proposal is NOT 
to disallow xml:base within the content of messages, but only on the few 
elements such as "envelope", "body" and "header" that are defined by SOAP 
itself.  We had strong feedback from some members of the workgroup that 
forcing all SOAP processors to honor xml:base in these situations would be 
a significant barrier to deployment, at least in the short term. According 
to the proposal, applications are free to allow xml:base within the 
content of a header or body, as long as they are prepared to honor it. The 
proposal goals on to say that bindings of SOAP to particular transports 
(such as HTTP), as well as features built on SOAP (e.g. SOAP+Attachements, 
which uses multipart MIME)   can establish a base URI for messges passed 
over that transport or with that feature;  in such situations, relative 
URI's can be resolved without use of xml:base, if desired.

Also:  the proposal was an attempt to capture the sense of the protocol 
workgroup's will.  I am moderately comfortable with it, but it is not 
really "my" proposal.  I think many of us feel that xml:base should be 
allowed on SOAP elements eventually, and the question is when.  There is 
strong sentiment among at least some wg members that now is too early.

Thank you.

        Subject:        XML Protocol WG requests comments by XML Core WG on position on XML Base

Dear XML Core team,

The XML Protocol group would like to ask the XML Core working group for 
feedback on a position it is contemplating wrt XML Base.  The proposal by 
Noah Mendelsohn at [1].  In summary, it proposes that SOAP 1.2 should 
disallow the use of xml:base attributes on SOAP elements, and leave 
undefined the behaviour of relative URIs.

I'd like to have this on Wednesday's agenda if possible.  I think our 
options are roughly
1) The text and premise are fine
2) The text and premise aren't fine, and here's the reasoning why.

Cheers,
Dave Orchard
