[xsd-users] Empty enumeration results in cxx value

[Stephen James]

So this does do what I need, except that when I serialize using the
empty enumerator I get <tag></tag> instead of <tag/>. The latter is what
I would prefer limiting the size of the xml, which is included in
messages.

Sorry, I was using the development build of XSD which uses a newer 
version of the Boost regex library. The following equivalent
expression works for me with the 3.2.0 binaries:

--enumerator-regex '/^$/empty_value/'
