Hi all,

just realised this flaw in my own thought-train:

euh... still inviting anyone to comment on the :name: notation
but the $keyword in combination with <xsl:param> probably isn't a good way
of taking up both keyword and named regex handling...

current feeling is that *if* the $keyword would contain parentheses then
they should be considered to be matched literally (more as \( and \) that
is)

having nested named regexes is a very different thing, which calls for a
different notation

still there remains the question about how perl does it (more general: what
would be logical to regex environments without breaking the xslt environment
(or vice versa))
