I (hope) I never said that this is against the rules. Ok, let's step back
and see where my thinking comes from (I might be wrong, though, in which
case I'd be happy to learn - from Yves or from whoever ;)

1. We want to specify W3C REC for a *syntax* for URI fragments in order to
address spatio-temporal fragments of media items.

2. In order to become a W3C REC we need to go REC track, including Test
Cases (for CR exit).

3. In order to write Test Cases for our spec, the semantics of the URI
(fragment) addressing a certain media fragment must be defined somewhere
(most likely in natural language, though I would love to do this in, say,
Prolog ;)

I've recently gone through this in RDFa. No fun without the paper trail,
believe me. TAG would most likely tear us apart before we knock on their
door.
 
Cheers,
      Michael
