Hello www-smil,

While reading

Synchronized Multimedia Integration Language (SMIL 3.0)
W3C Working Draft 13 July 2007

I noticed several instances of the word 'must' in informative sections. This is problematic, due to the common usage of 'must' as a conformance requirement in W3C specifications.

Please either 

a) reword these sections to avoid 'must', or 
b) add clarificatory wording regarding use of 'must' in the specification as a whole and noting any relationship to RFC 2119, or
c) consider making some of the informative sections normative, if 'must' is indeed used as a conformance requirement in some cases
