CORBA3 — pragma prefix syntax

suppose the following [pseudo-]idl:

#pragma prefix "2abc.def"

module xyz {
interface q

;
};

It would generate a Java class 'q' within package 'def.2abc.xyz'.
The package name '2abc' is not that popular with the java compiler
since it starts with a digit.

From what I could see in CORBA 2.6.1, identifiers have to start
with a character (or at least not a digit). So, I guess that the
prefix pragma is erroneous here, right ?

The OpenORB IDL parser 1.2.0 did though generate Java code without any
complaints, which confuses me ...
