The type declaration is based upon xs:double, restricting
further by the use of pattern should mean the two patterns are ANDed
together. I was working
on a vague assumption that . works like a 'super' character
class for ANDed patterns.
I'm not convinced about the use of . either - However, since I
find regular expressions as much fun as pulling teeth, I thought I'd
give it a go..

I may well take you up on that offer!
