| Okay, my bad.  Then there's a bug in the core parser, since it doesn't
| accept these.  The toplevel 'vdef' non-terminal expects first a qname,
| which is "name" or "mname '.' name".  However, according to the lexer,
| name must begin with a lower-case character...should this be changed
so
| that 'vdef' becomes "name" or "mname.name" or "cname" or
"mname.cname"?
