ISSUE-281 (non-inherited style initialization): Non-inherited style initialization needs specification prose. [TTML 1.0] http://www.w3.org/AudioVideo/TT/tracker/issues/281 Raised by: Glenn Adams On product: TTML 1.0 The rules for specified style set processing [1] do not adequately address initialization of non-inheritable styles when there is no other overriding value. I propose to address this in the TTML1SE errata by adding the following correction: <quote> In section 8.4.4.2, add the following step (7): 7. [non-inherited style initialization] if the element type of E is not the styling element type style, then for each non-inheritable style property P(NON-INH) that applies to E in the set of style properties defined above in 8.2 Styling Attribute Vocabulary, perform the following ordered sub-steps: * if P(NON-INH) is present in the specified style set of E, SSS(E), then continue to the next non-inheritable style property; * set P′ to the initial value of property P(NON-INH), where the initial value of a property is determined according to the specific property definition found above in 8.2 Styling Attribute Vocabulary; * if the value of P′ is not undefined, then merge P′ into the specified style set of E, SSS(E). </quote> This step should also be added directly to TTML2.
