Ah I think that is a reasonable comment, there is a historical issue
here that I don't think we should go into.

What we need to do as a minimum is to make the Respond tag
more descriptive, one option would be to use <Return>, although
that could be confusing. In SAML we used <RespondWith>.

So the request would be something like:

<RegisterRequest>
	...
	<RespondWith>X509Cert</RespondWith>
	<RespondWith>PrivateKey</RespondWith>
	<RespondWith>PGPKey</RespondWith>
</RegisterRequest>

This might be an argument for adopting the hierarchical structure
in the requests and responses etc.

That would allow the logical aspects that are common to the 
request/response structure to be factored out into a separate
piece of text.
