Fwd: [AXIOM] Undeclare default namespace

[Xinjun Chen]

Hi AXIOM developers,

I have some problem undeclaring the default namespace in an OMElement.
I have tried the following three ways but all failed. The default namespace
is still in the OMElement.

#1:
       OMElement reqElement = ....;
       reqElement.declareDefaultNamespace("");

#2:
       OMElement reqElement = ....;
       reqElement.declareNamespace("", "");

#3:
       OMElement reqElement = ....;
       OMFactory omFactory = reqElement.getOMFactory();
       OMNamespace ns = omFactory.createOMNamespace("", "");
       reqElement.declareNamespace(ns);

Could anyone point me out what I can do to undeclare the default namespace
in AXIOM? Thanks for your help in advance.

Regards,
Xinjun
