Dear SYMM WG- This is a Last Call review comment from the SVG WG on the SMIL Timesheets 1.0 specification, W3C Working Draft 10 January 2008, http://www.w3.org/TR/2008/WD-timesheets-20080110/ . Please let us know if you have any questions by replying to www-svg@w3.org. It's not clear that setting the 'active' or 'inactive' status of an element toggles its visibility. This should be stated in the abstract or introduction. The abstract should describe the primary use cases, which seem to be slideshows and photo galleries. Are there other use cases, either now or planned for future versions? --- It would be useful to explain very early on, in the abstract or introduction, that "active" and "inactive" refer (exclusively?) to states of perceivability, and that the purpose of timesheets is to switch between these states. --- "XML-based languages" Can timesheets be used with text/html documents? Maybe you should say DOM-based syntaxes? --- Throughout the document, it's sometimes unclear when you are making normative statements. We suggest strict use of the RFC 2119 keywords ("MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL"), in either upper or lower case, instead of looser terms like "are", "has to", etc. This will clarify the spec for implementors, and will also make it easier to develop a comprehensive test suite. We also recommend that you mark informational asides as such. Subsequent emails will point out specific instances that we feel need addressing, but there may be more. Regards- -Doug Schepers, on behalf of the SVG WG
