I'm just a newbie to XSLT. But you're of course right.

It does, but only twice. There are three elements here, so $before gets 
three values:

[\.\?!]+

[\.\?!]+

and

[\xff61\x3002\xff0e\xff1f\xff01]+

which is a ICU regular expression, and this seems to make Saxon complain 
(rightly).

Thanks for pointing this out. I thought Saxon was evaluating the first 
expression when it complained about the escaped sequence.

I'll need to build a Java API to use ICU regexps from the icu.jar 
library. But at first I wanted to check the design of the template with 
XPath regexps. Seems like I'd have to tweak the test data to build the 
first version of the template.

Thanks again,
