[mpeg-OTspec] Draft ballot comments for 3rd edition OFF text

[Levantovsky, Vladimir]

Hi Cameron,

Okay, assuming that there are no objections from the group let's adopt the first approach and make reference to SVG Integration normative. In order to finalize the comment I do need an exact language you want to see in the spec replacing what we have currently in place.

Thank you,
Vlad

We do reference it when describing the secure animation mode, however, the normative requirements for scripts, external references, etc. are explicitly defined in the text of the OFF. For the changes you suggested (i.e. remove UA style sheet definitions in OFF and reference them from SVG Integration document) - the document would have to be made normative. Do you know when the document is going to be finalized?  It would be good to have it moved to at least Last Call status before the OFF text is published (which is expected to happen in April - July 2015).

If this is acceptable, please suggest the exact language you want to see in the spec.

That would mean that if we do have any descriptions of the requirements in the OFF spec, that they are basically an informative summary of the "real" requirements that exist in SVG Integration at the time OFF is published, but subsequent updates to SVG Integration would override those summaries.

Doing (2) and allowing SVG Integration to be updated as new SVG language features are developed and expecting OFF implementers to follower the SVG Integration updates sounds like making the reference informative just to satisfy process requirements with the understanding that implementers really treat it as a normative reference.  I'd rather be clearer about what is normative.
