The xlink:type value MUST be provided in the infoset resulting from parsing an
XML instance using the provided schema.  In our schema, the
Reference@xlink:type attribute is fixed, meaning it is optional in the XML
instance but required in the infoset (and will always have the value
"simple").  Section 5.3 of the XLink Recommendation uses exactly the same
schema mechanism.  I don't believe a change is required here.

Agreed.  Isn't it fun tracing everything back to RFC 2822?

I'm not entirely certain what the issue is here.  Are you commenting on
another ambiguous interaction between the CPP/A or BPSS documents and an ebXML
Message conforming to those requirements, something similar to our earlier
discussions around the Service and Action values?  If I remember correctly,
those earlier discussions were resolved (after discussion between the TC's and
with UN/CEFACT) in the CPP/A or BPSS specifications.  Our current
specification certainly does not describe the specific source in a BPSS or
CPP/A instance for the Service or Action values.  Are you suggesting a
different approach for the Role element value or am I missing the real issue?
