I've marked as "blocking" since this prevents implementing document setup 
participants based on contentType and I don't know of a good work around. [Note: 
I believe the "ant based document setup" works simply because it also uses 
extensions.]

I've tried to create a simple setup participant as follows (note: no extensions 
used deliberately):

	<extension point="org.eclipse.core.filebuffers.documentSetup"
		id="com.ibm.sse.model.xml.XMLDocumentSetup.xml.xmlsource"
		name="Structured XML Document Setup">
		<participant
            contentTypeId="com.ibm.sse.model.xml.xmlsource"
			class="com.ibm.sse.model.xml.internal.filebuffers.
SetupParticipantForXML">
		</participant>
	</extension>


I've encountered several bugs in doing so, but the first one was that it seemed 
not to be getting detected/registered correctly. If I understand this code 
right, there seems to be a copy/paste error in 
getDocumentSetupParticipants(contentType), as fixed by following simply patch
