Hi Tommy,

note that the schema is only needed in certain usage scenarios.  In 
these scenarios, the schema identifies ID attributes so as to help the 
server resolve <ds:Reference>s.  The schema doesn't have to be the full 
schema for the document.  So even if the full schema imports other 
schemas, I think it's possible to chop down such a schema into a single 
one that contains everything needed?

ps: When the <Schema> element is described in the core spec, it refers 
to "section 4.3, step 2".  Those references should be changed to 
"section 4.3, step 1".
