thats just the syntax, i assume?

the features it supports, as opposed to the user syntax

oh, you've read the XSL spec then?

if they get more than 10% failure, why in heaven do they persist? it

probably it is. a typical data entry firm will get you *very* high
quality useable eg SGML files. predictable cost, predictable
processing. no more catcodes.

since XSL does not exist, your informant clearly has Powers.

sounds like a computer reincarnation of me

yes. but we'd be playing in the same swimming pool as the rest of the
