Describing TC-defined extensions

As we are working on extensions, one question to address is whether 
there is a need for Producers to describe all the types used for these 
well-known extensions beyond saying that it supports the extension by 
the QName.

I'm bringing up this question since the TC is defining QNames for these 
extensions, and consumers supporting the extension should have no 
trouble understanding the types used for that extension. The only 
exception I see is when a producer is overloading the extension QName 
for its own proprietary extensions.
