ISSUE-97 (metadata content model): Poor specification of metadata content model [DFXP 1.0 (Editorial)]

http://www.w3.org/AudioVideo/TT/tracker/issues/97

Raised by: Sean Hayes
On product: DFXP 1.0 (Editorial)

The current content model for <metadata> is  
Content: {any element not in TT namespace}*

This used to work, as the only non TT namespace element we had were in the ttm: namespace. But we now have captured the ttp:profile element as an allowed (syntatical) element here, but this has no semantic meaning in metadata. 

In order to avoid such inadvertant captures in the future, perhaps we should restrict our use of 'not' in these models to only content outside any tt namespace, and be explicit in our inclusion of tt namespaces.

Content: ({any element in any TTM namespace} | {any element not in any TT namespace})*
