However, the other main reason that doesn't raise an error is that
ancestor-or-self::foo evaluates to the empty sequence in the context
of that document and that way the multiplication also evaluates to
the empty sequence.
Yup, You're a star! :D
As Mike Kay points out separately, it’s a problem when a language gets
so terse that almost any string of puctuation has a meaning.
With regular expressions i tend to write [(] and [)] because i can
never remember in which sytaxes \(...\) is special, same with [{]
braces [}]. There can be an efficiency overhead for doing this, but
there’s a bigger efficiency overhead in time lost from a confused
developer :)
Similarly, avoid using XPath axis names as namespace prefixes :-) :-)
