Hi Daniel (CC to the EPUB and Voice-Browser working groups), I have reactivated this HTML5 issue [1] which proposes the adoption of a "pronunciation" link/rel extension [2], in order to provide first- class support for PLS pronunciation lexicons within HTML pages. In the upcoming v3.0 of EPUB [3], PLS files can be included at the publication level (i.e. not on a per-HTML file basis), so EPUB doesn't actually depend on this particular link/rel extension (it relies only on the "application/pls+xml" MIME type). Based on Ian Hickson's comments in the W3C bug tracker, it seems that a proposed "rel" extension gets accepted once the submitter can prove that it is adopted: "You'll need to write a spec first, and demonstrate that people are using the keyword. ... Please let us know once this keyword is deployed, for reconsideration." Consequently, I am tempted to propose a small addition to the EPUB3 specification, so that XHTML5 documents in a publication can reference PLS files, just like CSS files (providing they are declared in the EPUB manifest, of course). EPUB would therefore showcase a concrete adoption of the link/rel "pronunciation" extension, which would help moving its status from "proposal" to "accepted" in the HTML5 working group. I don't believe this is a requirement for "rel" extensions to actually work, but it would be nice to get official endorsement, especially given that this is pretty much a critical issue with regards to content accessibility. Comments welcome.
