Yet the description you gave went all the way to 'using' the slide set
in a dynamic manner, that's why I wanted to understand the scope of
the changes you talked about.

If we constrain the docbook work to markup only, I'd be happier.

If you can look after the 'S5' end, and just keep the discussions here
on markup, is that workable?

Should they be in a foils namespace, being a docbook extension?
(At least for db5)
Where (in the schema) are you adding them?

Which exactly mirrors what xsl-fo does :-)
