- variable in XPath seem to be allowed / disallowed in random ways.
A variable is allowed in precisely the same places as you can use a
literal value or a function call. What is random about that?
Unless of course you are desperately trying to make them behave like
macros. If you get your concepts that badly wrong, then you are going to
be confused.
