Yes, that's normal behaviour. In fact, the responce for XQuery may be 
any XML (or even not valid XML, just a string without root element), so 
we decided to encode XML. Of course in most of cases the content will be 
NMWG but we cannot guarantee it.

Services register by themselves, so perhaps the mistake is in the 
registration message. LS stores everything what was sent to be registered.

You must use <eventType>...</enventType> inside subjests. Now I don't 
have the details for that, but you may see the example of query request 
(LSLookupRequest) on the SVN (or the tarball release) in 
schema/example-instances/.../LS/test
(sorry for not providing you all the details but I am on the meeting and 
have just configured network) :)

If it doesn't help, let me know, I'll provide more details.

Best regards
