ISSUE-417: #writingMode constraint inconsistent in image profile

#writingMode constraint inconsistent in image profile

State:
CLOSED
Product:
TTML IMSC 1.0
Raised by:
Pierre-Anthony Lemieux
Opened on:
2015-09-21
Description:
TTML1 states

"""[...] supports the #writingMode feature if it recognizes and is capable of transforming all defined values of the tts:writingMode attribute."""

IMSC1 common provisions state that "#writingMode MAY be used", but the image profile state that "#writingMode-vertical SHALL not be used."

So #writingMode should be removed from common provisions and moved to individual profile provisions.

Addressed at https://dvcs.w3.org/hg/ttml/rev/6008e9f4b4bf

#writingMode is now described as "Not applicable since some, but not all, implied features are permitted" in the image profile and as "May be used" in the text profile.
