[oXygen-user] an xslt challenge

[James Cummings]

Hi Lou,

Yes, it does suggest for each paragraph you'd be tokenising (or grouping)
into sentences, which might have a slight efficiency hit (but I doubt that
much), but would make the choosing the number of sentences to be under
$maxWords easier. I was assuming that you wanted the output to have the
sentences marked as <s>, my mistake.
