Document type declarations for SSML?

[murata2makoto]

Do we need document type declarations for SSML? Since SSML is always embedded within an HTML content document, document type declarations for SSML are unusable. Do people agree?

This issue is to create § B. Allowed External Identifiers as proposed in #1368.

[mattgarrish]

The SSML attributes were our own extension of HTML. There isn't a DTD for them and they can't live anywhere else unless someone else defines their own implementation.

This issue was discussed in a meeting.

Wendy Reid: we had resolutions at the F2F, and further discussions on github
… and came to a happy place
Matt Garrish: #1368
Matt Garrish: where we ended up was…
… we put in an allowance for a specific set of external identifiers that we have put in an appendix
… we have SVG and MathML that are allowed to be used in content docs or in separate files
… and we made a restriction against external entities in the internal DTD subset
… so it prevents some security issues but eases authoring
… so we’ll no longer force people to remove SVG DTDs from tool-generated files
… I’m hoping this is it :)
Ivan Herman: tech comment
… in fact, the changes are such that
… makes possible something that I’m not sure we really use
… I can define as part of an internal entity something that won’t go out to the network
… I’m not sure if this feature is in use
… formal comment
… there was a formal resolution on the previous version; this PR slightly changes that
… can we get a formal resolution to merge, and also close a bunch of issues which were examples of the problem?
