Ok, precision is a good point "to evolute" this 
discussion...

Do you think that W3C can publish other "W3C Note" with 
a vCard-XSD?

The "TR/vcard-rdf W3C Note" express a W3C position regarding
the XML-vCard subject, or we have space to a XSD?

Do you think that they has, between RDF and XSD "formalims",
some kind of the conflict? (in then context of vCard def.)
(xsd:Tag is more complex or dirty than Tag;
 if you have XSD you don't need a RDF seq/li and alt/li
 )

Do you think that XML-vCard (as a RDF or XSD) is a IETF 
or a W3C responsibility?
(to produce a standard/Recommendation)

Yes, we need, to really work with XML-vCards, a "approved XSD"
for vCard... where it is?? With what we can start?

Do you think that the name spaces "induzed by" 
dawson-vcard-xml (name, prefix, etc.) and by w3c-vcard-rdf 
(N, FN, etc.) have conflict?

!!?? You can do this?? I am a little ant...

(poor pupils.. ;-)  can I see the works, you have a URL?)

(ietf-vcard-xml in www.imc.org is died?)
([email protected] is alive?)
(we can consolidate the mail-lists in a ietf place?)

I think that we need first expose de conflicts to next
find consensus (about then) and next do new work (new XSD, 
new semantic remarks, etc.).

Yes... but it never is late for starting... 1 and 2!
I think a little group can start with 2 then go to 1.
Much people will be contented with point your XML 
or refs. to 2.


Final notes:
 I think RFC-2426 not "very fineshed" one... In Brasil, f.ex.,
 the name tags, N and FN for the name property, not sound
 well: we don't use "Family, First-name" lists usualy, and
 databases have only "First-name middle Family" monolitic 
 format, and this format have not the semantic of FN... 
 N and FN can not "well-used" into the standard vCard in 
 Brasil. The major "name databases" (hospitals, government, 
 private big orgs) are today in "monolitic" format in Brasil.
 We also have a lot of composite names (f.e. "Fernando Henrique",
 the president's first name) and RFC-2426 not very clear for
 this.


PS: sorry my english...
