ISSUE-341: ambiguous definition for determination of descendant region identifier [TTML 1.0]

http://www.w3.org/AudioVideo/TT/tracker/issues/341

Raised by: Glenn Adams
On product: TTML 1.0

Step 3 of the [association region] procedure in Section 9.3.2 is ambiguous if multiple descendants are associated with a region (possibly distinct).

Suggest changing from:

"if the element contains a descendant element that specifies a region attribute, then the element is associated with the region referenced by that attribute;"

to

"if the element contains a descendant element that specifies a region attribute, then the element is associated with the first region referenced by that attribute using a breadth-first pre-traversal search of descendant elements;"
