In Orbeon Forms, @ref can return any sequence of items, not only
nodes. Now the question is whether the working group in fact decided
to do this. Nick, do you remember the details?

The XForms 2.0 doc right now says [1] "Binding expression interpreted
as specified in the expression module."

The XPath Expressions Module [2] defines a Binding expression as "An
[XPath 2.0] expression used in a binding". But certainly it should
address the fact that a binding expression does not necessarily point
to nodes, and how it deals with atomic values. Right now I don't find
anything on that topic in the spec.

Nick, do you have any feedback on this?
