RE: [xsl] check the type of the $pattern argument to a regular expression?

["John Horner" <Horner.John@xxxxxxxxxx>]

I agree with the people who think a pattern to test patterns is an
insoluble problem.

There are an infinite number of valid regular expressions, and an even
larger number of invalid ones. Plus all those inbetween regular
expressions which are valid, but not what you meant.

It would make far more sense for you to test your regular expressions by
some other means before putting them into your XSL.
