In a few days a WS-I representative will meet with W3C representatives to
discuss the relationship between the two organizations. I hope some well
defined process will be put in place soon to facilitate the exchange of
information between the two groups.

We should also keep in mind that, so far, WS-I is only addressing version
1.1 of SOAP and WSDL (versions which don't even have standard status). It
will be more interesting to see how WS-I will approach SOAP 1.2 and WSDL

In any case, any WS-I deliberation concerning the 1.1 versions will probably
have direct effect on current/near future use of Web Services, and will
shape people's expectations regarding the next versions of Web Services
components. As you say, it's something we definitely have to be aware of
and, possibly, publicly comment on.

Hmm, since the type information defined in a schema is part of the PSVI and
not the InfoSet, I guess my suggestion to not rely on the PSVI in a web
service was not well thought through ... still, I think the security
implications of default and fixed attribute values is something that we may
want to address.

Also, this reminds me that we need to think about this WG's relationship
with the WS-I.  I suspect that most of our companies are WS-I members, so
we'll have access to information about their deliberations, but we need to
be careful about whatever confidentiality guidelines WS-I may impose.  I
[personally, not wearing chair hat] think that we need to "harvest" WS-I
conclusions/recommendations and either a) endorse them; b) note caveats that
may make them less relevant in the future; or c) counter them if we really
think they are not in the best interest of the overall web/web services
architecture in the long run.
