[glenn]: mike should review, but WG appears satisfied

19 Sep 2013, 14:54:52

Although a warning note is an improvement, I'm not sure a reader will find it any easier than understanding in general the details of inheritance and undefined semantics. I believe we should consider forbidding non-inheritable attributes from being placed on elements for which there are no defined semantics. This would theoretically be non-backwards compatible with TTML1, but any document doing this was probably authored in error. The XML schema can be updated to reflect this change and thus flag such usage.

NIgel: P2 for Mike and see if he pushes it

Philippe Le Hégaret, 24 Oct 2013, 15:24:38

This issue is not resolved per my comment above. This issue has led to poor/fatal interop, e.g. the erroneous and vendor-specific semantics for origin and extent on <p>. Non-inheritable attributes with no semantics on an element should not be permitted.

Mike Dolan, 1 Nov 2013, 17:49:04

It is my intent to not prohibit specifying styles on element that are not inheritable and don't apply to the element. The specification is well defined that such a style specification is to be ignored. Authors should use content validator/verifier tools that warn about such redundant usage.
