ISSUE-97: Poor specification of metadata content model

metadata content model

Poor specification of metadata content model

State:

CLOSED

Product:

TTML 1.0 (Editorial)

Raised by:

Sean Hayes

Opened on:

2009-05-15

Description:

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