119676 - Assign non XUL attributes to a non XUL namespace

Status: NEW

(Core :: XUL, enhancement)

Description

[Peter Wilson]

Currently Mozilla XUL uses arbitary additional attributes on XUL elements to
pass data values to the program processing the XUL. 
e.g. errmsg etc.
These additional attributes should be assigned to a different namespace than 
XUL.

1. This would aid documentation efforts as these attributes would, plainly, not 
be part of XUL.
2. A number of efforts are under way to use XML Schema or Relax NG to describe 
XUL so that syntax checking will be possible. The additional attributes can only 
be accommodated by the equivalent of attribute:any on an element description.
This defeats syntax checking as any mis-spelling of a legitimate attribute will 
be silently picked up by the "any" catch all.
3. A similar usage should be adopted for non XUL elements.
4. The use of the <data> element which is also used in XUL for program data 
should be legitimized and documented.

Yes, this will also be important for schema validation.

Should we file a separate "bug" for reserved tagnames for future versions 
of XUL so that those dont get stepped on by other implementers?
