I would suggest calling the attribute "parameter_pack" or "pack", rather
than "variadic", since it's more precise. One could even do the same for
<parameter name="args" pack="1">.

I think you have the right idea.

The stylesheet to generate the BoostBook reference from the dtdxml

Actually, when you re-run bjam in tools/boostbook/doc, it should
regenerate the appropriate BoostBook input from the dtdxml document.
