Pronunciation lexicons, proposed link@rel extension

Hi all,

I recently presented [1] the work we are doing to support speech  
synthesis within EPUB publications. As part of this initiative, we  
propose a "rel" value ('pronunciation') for the "link" element in  
(x)HTML documents. The dedicated WhatWG wiki page [2] is now obsolete,  
and the "rel" extensions are now recorded on the Microformats wiki [3].

Our simple proposal [4] enables the inclusion of pronunciation  
lexicons (based on formats such as W3C PLS) in web documents, just  
like CSS stylesheets. The upcoming EPUB v3.0 standard will demonstrate  
a concrete use for the 'pronunciation' link@rel value, so I believe  
that the HTML5 working group / implementors will eventually be enticed  
to promote and support pronunciation lexicons. :)

Your thoughts are welcome, and please feel free to edit the wiki  
directly!
Many thanks, Daniel
