Related notes:
TTML1 states:
"""
A TTML processor supports the #bidi feature if it supports the following features:
#direction
#unicodeBidi
#writingMode-horizontal
"""
So #bidi cannot be used as soon as one of its dependent features, e.g. #direction, is not supported, right?

#bidi 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.
#unicodeBidi is described as "Shall not be used" in the image profile.
[nigel]: [meeting 2015-10-15] Propose new text: "See implied features: some are prohibited, others are permitted"
