PRD02 Pr 1 19.444 schema incompatibie with SMIL

[Alex Brown <alexb@griffinbrown.co.uk>]

Dear all,

19.444 (smil:endsync attribute) directs us to 10.3.1 of the SMIL spec.

The W3C rec, in its wisdom, has recognized that such attributes, being overloaded, pose the danger of being subject to an ambiguity in which it is not possible to determine whether a value (say "media") is the pre-defined token value, or a reference to some ID value "media" elsewhere in the document.

Accordingly they state:

"For the purpose of parsing the endsync argument value, first, last, all, and media are reserved words and must be escaped with a backslash in order to be used as Id-value's"

However, the ODF schema does not permit the escaped form of these values (since the escaped form is not a valid IDREF).

Please align ODF with SMIL by correcting this defect in the schema.

- Alex.
