OpenSAML user discussion

To enable greater compatibility with some of our existing implementations of 
code, I am looking to change the namespace declaration on the marshalled 
objects but haven't found a way to do this.

Currently have (for example):
<xacml-context:Request 
xmlns:xacml-context="urn:oasis:names:tc:xacml:2.0:context:schema:os">

Ideally would like to have:
<Request xmlns="urn:oasis:names:tc:xacml:2.0:context:schema:os">

I have tried to clear the namespaces and add a new namespace with no prefix 
as follows...

<code>
RequestTypeImplBuilder xacmlRequest = (RequestTypeImplBuilder)builderFactory
              .getBuilder(RequestType.DEFAULT_ELEMENT_NAME);

RequestType request = xacmlRequest.buildObject();
request.getNamespaces().clear();
request.getNamespaces().add(new 
Namespace("urn:oasis:names:tc:xacml:2.0:context:schema:os", ""));
</code>

...but I get an java.lang.UnsupportedOperationException thrown on 
request.getNamespaces().clear();. I have also tried passing in a new 
QName("urn:oasis:names:tc:xacml:2.0:context:schema:os", "Request", "") in 
place of the RequestType.DEFAULT_ELEMENT_NAME to the builderFactory but that 
has no effect.

Is it possible to do this? I am using opensaml 2.1.0.

Thanks,


Christina
