Hi Frans,
You are right, it's there, I didn't notice this regex flag before.
But it does not allow for comments in the construct, it allows only for
extra whitespace. And I need comments, otherwise the extra whitespace
helps only a bit.
Cheers,
Abel

Dear List,
The regular expression syntax used in XSLT and XPath is largely based on
Perl's regular expression syntax. Perl added a very useful construct to
their regular expression dialect: the /x modifier. It gives "whitespace
freedom" and allows for comments inside regular expressions. It was a
great enhancement at the time, especially for moderate to difficult
regexes.
As I see it, XPath 2.0 has that flag too. See XQuery 1.0 and XPath 2.0
Functions and Operators, section 7.6.1.1 Flags:
