Erm, can you cite a reference for XHTML+SMIL being a REC?

Yes, your markup is unsupported.

That appears to be in order, in principle at least.

That is totally bogus.  The "error" is arising not in your page,
but in the DTD modules.  Code Valet reports it as


At http://www.w3.org/2001/SMIL20/WD/SMIL-anim.mod, line 50, column 34

parameter entity "BasicInlineTiming.attrib" not defined

The underlying problem seems to be that the DTD you have used is
incomplete, and even bears a big "UNDER CONSTRUCTION" comment.

> What do I need to do in order to make this XHTML+SMIL document validate?

Alerting this list to the problem could be a good second step, after
checking the status of your DTD:-)
