What are the useful functions for accessing the area tree?

If you look at the current 'ppl-extensions.xsl' [1], you'll see that the
only current helper functions for accessing the area tree are
ppl:block-by-id() and ppl:block-bpd() which, by some coincidence, were all
that were needed to do the current examples.

What are the useful functions that we could provide to help shield the
stylesheet writer from the full gory details of every implementation's
area tree format?

Regards,


Tony.
