I'd leave the answer to the HTML WG, but I guess one of the difficulties is that the role attribute can be attached to arbitrary elements, including elements in non-XHTML namespaces, so you cannot predefine which element can have the role attribute (as opposed to e.g. the target attribute, the XHTML Target Module specifies which elements in the XHTML namespace can have the target attribute). For better or worse, the number of elements in the XHTML namespace is not quite fixed, either. In the meantime, you could add something like the following in your customized DTD (after instantiating the XHTML Role Qname Module but *before* instantiating the XHTML 1.1 DTD): <!ENTITY % Common.extra.attrib "%xhtml-role.attrs.qname;" > This will allow the role attribute on most (but not all) elements. -- Masayasu Ishikawa / mimasa@w3.org W3C - World Wide Web Consortium
