What additional markup is needed? A lot, or just minor additions?
That's an interesting question. The obvious addition would be support
for incremental slide presentation. This includes incremental list
items, as well as other incremental content, but it also includes
graphics overlays. (I abused the mediaobject semantics, which already
allows multiple imageobjects; I changed the semantics to mean that all
imageobjects inside a mediaobjects are to be overlayed, and displayed
incrementally.)
Wow, this gets messy. IMHO that is too close to the physical
presentation, i.e. showing it to the audience, i.e. how html is
shown in the browser, than the simple 'presentational markup'
Where to draw the line? Overlays and slides are javascript + html
surely? Same way that Norm added 'next slide' type javascript.
What markup are you thinking of for incremental lists?
list continuation attributes? Semantic = continue numbering from
previous-sibling::list?
Another area is to explicitely allow multi-column displays, with
explicit placement into those columns (or more generally, blocks).
Having content flow automatically is typically not what presentation
authors want.
Which is getting pretty close to xsl-fo? Again, where to draw the line?
I've used CSS for multi-column presentation of html divs... how to get
that back into markup?
By the sound of it you want n divs, then a means to lay them out?
perhaps using some <sect-n> element with an attribute indicating left
or right layout? is that the sort of thing?
There is certainly much more to be done. I'm not a presentation
power-user,
<chuckle/> you are, compared to what I've used slides for!
so my use-cases are rather minimal.
But this is a start. Or actually, moving docbook-slides to DB5 would be
the start. <wink/>
A couple of us moved website to db5 in a week or two. Same effort for
slides I think.
I'm not 100% at the moment or I'd offer to do it. Not hard though, honest.
