Dear Markus, First of all, please meet, in virtual space, Robin Berjon, one of the editors of the HTML5 spec and also fellow team member at the W3C. Robin, please meat Markus Gylling, CTO of IDPF and also possible chair of the upcoming Digital Publishing IG. Markus, I had some discussions with Robin on the question we were discussing a while ago you and me, on whether the @role attribute could be used in EPUB3.01 to replace the current idpf:type attribute for, say, glossary items. I just forward you the relevant issues; I let you two discuss the technical details, if any...
