ISSUE-55: make tts:textDecoration and tts:textOutline inheritable

make tts:textDecoration and tts:textOutline inheritable

TTML 1.0
Raised by:
Glenn Adams
Opened on:
Although CSS and XSL do not make text decoration or text shadow) inheritable style properties, they do require that their presence be propagated down to descendant inline areas. Semantically speaking, text decoration (and shadow/outline) only applies to inline areas, or, to be more precise, to glyph areas that compose inline areas. Since DFXP allows only presentable inline and block content element descendants of block level element types (e.g., body, div, p), it turns out that this application of text decoration (and outline) to descendant inline areas is equivalent to full inheritance; therefore, it would be better (and more consistent from a specification perspective) to make tts:text{Decoration,Outline} inheritable in DFXP.
