[SMIL21 CR comment] Depreciate smil:id in favour of xml:id?

Hello,

Just a suggestion, feel free to ignore.

In the latest SVG 1.2 Working Drafts, use of the 'xml:id' attribute is 
being encouraged over SVG's own 'id' attribute.  (The old 'id' hasn't 
been removed altogether, however, in order to maintain backwards 
compatibility.)

Similiarly I believe the next draft of XHTML 2.0 will utilise xml:id, 
yet have *no* native 'id' attribute.

Is there still time for the SMIL 2.1 spec to support this convergence to 
xml:id?

I appreciate that xml:id has not yet moved out of CR 
<http://www.w3.org/TR/2005/CR-xml-id-20050208/>, but still thought it 
was worth raising.

Thank you,

Dave
