Herve,

Thank you for drafting this, it looks to me like a good start.  One point 
of concern.  I don't think it's appropriate to say that a resource is 
"identified" by a URI reference.  As I understand Web architecture, 
resources are identified by URIs.  URI references are used to refer to 
such URIs, and they allow some convenience forms (notably relative) that 
require conversion (to absolute) before the referent can be identified.

<HervesProposal>
Each part is identified by a URI reference that can be used to reference 
it from other parts. The URI reference identifying a part can be of any 
URI scheme. It can be an absolute or a relative URI. The particular 
assignement of URI references to parts in the message MUST be specified 
by each SOAP binding implementing this feature. In addition, if a SOAP 
binding allows the use of relative URIs, it MUST specify how the base 
URI is established. It is RECOMMENDED that only IANA registered URI 
schemes be used.
</HervesProposal>
<NoahsProposedRevision>
Each part is identified by a URI, and the URI identifying a 
part can be of any URI scheme supported by the binding (see below). 
References to parts SHOULD BE in the form of URI references, 
which allow for both relative and absolute forms.  Fragment 
identifiers MAY be used when the media type of the part 
is known and if the media type supports the use of fragment 
identifiers.

The particular assignement of URIs to parts in the message 
MUST be specified by each SOAP binding implementing this 
feature. It is RECOMMENDED that only IANA registered URI 
schemes be used.  In addition, in order to support the use
of relative references, SOAP bindings SHOULD specify how 
the base URI is established. 
<NoahsProposedRevision>

I'm not sure about the fragid stuff, but I URI refs support them 
lexically, so we need to either say how to use them, or explicitly rule 
them out.  I can live with the above.  Thanks.
