It seems to be a fairly procedural approach and, while I have not seen
what these XSLT stylesheets do exactly, they appear to work in a fairly
deterministic way. XSLT is not ideal for procedural algorithms, but at
the end of the day it's just another language. There is a tradeoff
between doing things in a less-then-ideal, but available language
compared to an ideal, but less-than-available language. If you use XSLT
just for two internal things, the tradeoff may be on your side, if your
users start to write their own XSLT stylesheets to configure the
process, then perhaps the tradeoff falls on the other side. YMMV :)

cheers,

Ulrich
