Use of HelperContext to indetify SDO databinding?

[Simon Laws]

Static SDO used in the databinding tests with the Axis2 binding are not
being successfully identified as SDOs.
In SDODataBinding.introspect() one of the tests use to identify and SDO from
a Java type is as follows

       HelperContext context = HelperProvider.getDefaultContext();

       ...

       // FIXME: We need to access HelperContext
       Type type = context.getTypeHelper().getType(javaType);
       if (type == null) {
           return false;
       }

However when the ImportSDO functionality runs it associates the importer
with a HelperContext from the helperContextRegistry.

          helperContext = helperContextRegistry.getHelperContext(id);

This doesn't look right to me as I expect different HelperContexts will be
used. I can't work out how to get to the helperContextRegistry from the
SDODataBinding (and it's getting late) but if someone who knows databindings
could take a look and confirm or not whether this is an issue I can take a
look tomorrow.
