"Incompatible SMPTE ST 2052-1:2013 extension namespace name"

+

Issue number: #512
+ Raised by:@palemieux
+ Extra Labels: imsc1.1

+

Initial description: SMPTE ST 2052-1:2013 (SMPTE-TT) modified the extension namespace name originally defined in SMPTE ST 2052-1:2010, from `http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt` to `http://www.smpte-ra.org/schemas/2052-1/2013/smpte-tt`. [ed.: It is not clear why this change was made.] + IMSC 1.0.1 and IMSC 1.1 use `http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt` exclusively for the smpte:backgroundImage attribute. + IMSC 1.0.1 references undated SMPTE ST 2052-1. + IMSC 1.1 references SMPTE ST 2052-1:2013.

Erratum summary: + The normative reference: + > SMPTE ST 2052-1:2013 "Timed Text Format (SMPTE-TT)". SMPTE. URL: https://doi.org/10.5594/SMPTE.ST2052-1.2013 + is modified to read: + > SMPTE ST 2052-1:2010 "Timed Text Format (SMPTE-TT)". SMPTE. URL: https://doi.org/10.5594/SMPTE.ST2052-1.2010

"#extent-root implies support for #extent-auto"

+

Issue number: #489
+ Raised by:@skynavga
+ Extra Labels: imsc1.1

+

Initial description: IMSC1.0 specifies that #extent-root is permitted, and #extent-root implies support for #extent-auto (see note in TTML2 §E.1.92); however, IMSC1.1 does not include #extent-auto in §6, which would mean that #extent-auto is prohibited in IMSC1.1. This makes IMSC1.1 incompatible with both IMSC1.0 and TTML2 regarding the semantics of #extent-root.

+

Erratum summary: + > 8.4.2 #extent-region + > The tts:extent attribute SHALL be present on all region elements, where it SHALL use px units, percentage values, or root container relative units. + is replaced with: + > 8.4.2 #extent-region + > For each region element defined in the Document Instance, the [specified value](https://www.w3.org/TR/ttml2/#semantics-style-resolved-value-category-specified) of the tts:extent style property SHALL consist of two length expressions + > that use pixel (px), percentage (%), or root container relative units. +
