Yup, You're a star! :D

As Mike Kay points out separately, itbs a problem when a language gets
so terse that almost any string of puctuation has a meaning.

With regular expressions i tend to write [(] and [)] because i can
never remember in which sytaxes \(...\) is special, same with [{]
braces [}]. There can be an efficiency overhead for doing this, but
therebs a bigger efficiency overhead in time lost from a confused
developer :)

Similarly, avoid using XPath axis names as namespace prefixes :-) :-)
