Changes

XUL doesnand SVG don't define the <link> tag, an open question is how the roles can be included in such documents.

* One suggestion is to create a new processing instruction like: <code> <?xml-aria href="chrome://calendar/content/access/roles.json" type="text/json"?></code>(Note from Aaron, can we do this on a role by role basis for SVG? We have that advantage in the link solution for HTML)* Also, since XUL has XBL, and this is effectively a new widget, we could require that it be a new element. The nsIAccessibleProvider interface used in XBL could be extended to provide a property that points to the JSON file. Or, in XBL we could actually directly define the properties that would have been in the JSON.
