This totally alters decoder processing.  Apparently it needs additional explanation, but it is not metadata.

ISSUE-312 (forcedDisplay should be in ttm): forcedDisplay attribute is metadata so should be in ttm not tts namespace [TTML IMSC 1.0]

http://www.w3.org/AudioVideo/TT/tracker/issues/312

Raised by: Nigel Megitt
On product: TTML IMSC 1.0

The description of tts:forcedDisplay [1] does not define any change in processing behaviour so it appears to be metadata and should therefore be moved to the ttm: namespace.

Incidentally the note in this section references "forcedDisplayMode" which is not defined anywhere.
