RE: [xsl] Proposed syntax for namespace binding in XPath

["Michael Kay" <mike@xxxxxxxxxxxx>]

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.
