What I said in response to Heiko (or at least, what I intended to say)
was that there was not a limitation of the mobyData block to having just
one child element (regardless of its type - simple, collection, or
secondary).  So the following is vaid:

<mobyData>
	<Simple A/>
	<Simple B/>
	<Collection Q>
		<Simple/>
		<Simple/>
	</Collection> 
</mobyData>

I didn't say that you SHOULD return all of your Simples individually,
only that you COULD return individual Simples in a single output... if
that was meaningful in the context of your service... individual outputs
must, however, be individually registered in the registry 

(output => [A,B,Q])

That's right.... and obvious, since you cannot create a service
signature any other way - you can't say output => [A....infinite]

I don't see it.
