payload mapping and token security?

Good to know. I'm still investigating but it might be namespace related.
Thanks again

<q0:topicRetrieveRequest>
  <topicId>1</topicId>
</q0:topicRetrieveRequest>

I would expect that for the explorer version there is no need to specifiy the namespace of topicId because it is inherited from topicRetrieveRequest.

Prefixed namespaces aren't inherited. The <topicId> element is in a different namespace than it's parent element. Inheritence (at least in the text representation) could occur in the following (no prefix):

<topicRetrieveRequest xmlns="http://mycom.com/merged">
  <topicId>1</topicId>
<topicRetrieveRequest>

Basically, it looks like the explorer version is wrong, despite the fact that your service "works" Maybe no validation is occurring?

Your reply is helpful. I had expected the prefixed version to perform like the non prefixed example regarding inheritance, thanks for the clarification.
It is true I'm not validating - I had turned it off as I simplified (removing security tokens etc) to try to get something simple working before I made things more complicated. Perhaps I should have left validation on.
