I suspect the absence of a "like" function in version 1.0 is because people
didn't want to put regular expression matching in unless they got it right,
which with full Unicode and full internationalisation is not actually easy.

I don't understand what you mean about nested conditionals, XPath does allow
predicates to be nested.
