RE: Proposed syntax for namespace binding in XPath

That's all detail to be worked out.

It turns out that using comments has the same disadvantages as they had with
the original XQuery pragma syntax: they're handled in the tokenizer which
has no knowledge of the syntactic context. So I may look at using a
different delimiter after all. But I was thinking of recognizing this syntax
only if it occurs right at the start of the expression.
