Actually it was there from the start of my implementation due to an
incorrect reading of the spec - and I'd just joined the list so wondered
if it was worth adding for XPath 2.0. I don't (unfortunately) have an XSLT
implementation - much that I wish I had the time to build one (although
realistically does the world really need another XSLT implementation?).

Yes, I could do that. In fact it's an excellent idea. However what I'd
really like to see is proper C escaping in the next release, so that I can
just do "He said \"Hello Mum\"."

That's xslt - we're talking about XPath here.
