I didn't say they are dead, just that their status is in a practical limbo.  
The many tortured threads on how to fix this limbo on XML-DEV are ample fuel 
for this opinion.

An ID technically requires a DTD or XSD declaration, neither of which are so 
far required by WSDL.

Yes.  And XHTML requires DTD for this many reason (among others), and Ann 
Navarro of the XHTML WG recently sent a message on XML-DEV affirming that 
XHTML will have this dependence for a while.  I don't know that you want to 
require doctype declaration or schema location specification on WSDL 
documents, which previously did not have this restriction.

But you have to say exactly what IDs you mean.  DTD?  XSD?
