All,

There seems to be a problem with the mailsystem. Has anyone else noticed 
it? Nathalie and william are having their mail bounced.
Here is Williams last message.

My mail is not appearing on the list. Maybe it has bounced. Do you have
access to the JSDL mailinglist system? 


------------------------------
I agreed that Qname type can be used, however, it's been a controversial
type to use throughout the history of XSD, because interpretation of a QName
value needs contextual information (the enclosing elements and their xmlns
declaration). 

<jsdl:JobDefinition ...>
    ...
    <jsdl:CPUArchitecture>myns:sparc</jsdl:CPUArchitecture>
    ...
</jsdl:JobDefinition>

For the parser, it needs to resolve the "myns" namespace prefix from the
enclosing elements in order to deduce whether it's in the jsdl namespace or
others.

I'm easy both ways (token / qname), although I don't think going Qname makes
the definition any richer. I just want to point out the argument from an
implementers' point of view.
