Document type declarations for PLS?

[murata2makoto]

PLS does not have a DTD. It has an XSD schema and a RELAX NG schema. EPUB3 has used the RELAX NG schema.
Thus, we are not going to allow DTDs for PLS. Do people agree?

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

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?
