Is it possible to change a parameter element?

Hi folks, I have tried many ways to generate parameters (arrays and
Objects), but none of them worked.

I have a WS parameter (in the body of my envelope) which is being
generated like this:

<ns1:nfeDadosMsg>

But I need it to be generated like this:

<nfeDadosMsg xmlns="http://www.portalfiscal.inf.br/nfe/wsdl/NfeRecepcao2">

Is it possible? How can I do it?

I'd really appreciate your help.

Thanks in advance,

Zé Ricardo
