I think it would be better to avoid the duality that exists in XSLT between
patterns and expressions. A pattern should be an expression that returns true
or false based on evaluating some condition applied to the context item, so
that it can be used anywhere a boolean expression can be used. So if for
example the syntax [|pattern|] is used, then [|p|] is an expression that
returns true if the context node is a p element.
