Subject: [Moderator Action] XML Linking WG review of SMIL Last Call Working

>    The XML Linking WG recently reviewed the Last Call version of the
> SMIL 2.0 specification at http://www.w3.org/TR/2000/WD-smil20-20000921/
> (http://www.w3.org/AudioVideo/Group/ version was also checked).
>   Due to the size of the specification, only the parts likely to be
> to linking were reviewed, more specifically the Linking Module,
> the Language Profile and the Basic Language Profile.
>    First we would like to report our appreciation for your making the
> namespace declaration required in the Profile. There are, however, three
> points which would have to be checked or modified in the process of
> going to Candidate Recommendation and further:
>   - SMIL is not requiring XPointer and is making heavy use of fragment
>     identifiers in URI References to parts of SMIL documents.
>     Hence it must register its own MimeType and not be delivered
>     as text/xml nor application/xml.
>     It seems that, since this registration is a work in progress, it
>     must be made sure that it has attained a sufficient standard level
>     at the IETF before asking for PR.
>   - The Linking module suffers (as I reported back in March) some
>     namespaces deficiencies:
>       + the namespace must be specified before starting enumerating
>         the linking attributes and elements of SMIL, especially since
>         some attribute's names and values conflict with XLink ones.
>       + none of the full formed SMIL examples in that chapter includes
>         the SMIL namespace declaration; this is error prone for
>         implementors or authors and is not conformant to the SMIL
>         Language Profile
>   - The status of the use of XML Base is unclear. As explained in the
>     XML Base specification, the deployment strategy for XML Base is by
>     reuse in other XML specifications. Though there is a reference to
>     it in the Appendix B, it is unclear if it is normative.
>     There is also no reference to it in the Linking module. We hope you
>     intent to use XML Base and make it clear in the Linking Module.
>   We thank you in advance for the clarification those changes would
> make.
>   Sincerely yours,
> Daniel Veillard
