There is no such thing in the XDM data model as "a null string". If we're
going to discuss language semantics, let's try and be precise.

I can think of at least three possible meanings of "a null string" in other
languages: a variable of type string that has no value, a zero-length string,
and a string containing the single character NUL (ascii x00).
