I think this begs a question:  to what degree is what we're looking for 
grounded in any schemas?  In the case of the Schema WG's SCDs, the answer 
is yes by definition.  In the case of:  "The p element in the XHTML 
namespace.", there's a question as to whether that's in the collection of 
all possible XHTML schemas, as you suggest, or whether it exists in 
principle even if no schemas are ever written?

One answer is:  don't worry about it.  The original TAG use case was 
specifically in Simple Types, not elements.  Those are pretty well 
grounded in schemas, and so your argument holds.  For the element example 
you give, I'm less sure.  Shouldn't I be able to write a URI identifier 
for {XHTML,p} without first writing a schema?  Not sure.
