Yup, I understand; I wasn't really suggest that you introduce
this complication at this stage! Just checking whether it was already
hidden somewhere.  In my case, I'm guaranteed to have the schema
available for such information.

Not quite what I needed, since I'm doing document surgery all the
time.  I went ahead & implemented my own serializer, but it wasn't
really all that bad, since I could still rely on libxml's lower
level string munging :>  And surprisingly enough, no significant
performance penalty.

And it helped me simplify lots of bad heuristics! :>
Yay!

Thanks for the response;
