Thanks for the explanation!

No, indeed services_discovery_RemoveItem does allow removing any item at any
level of hierarchy. But it will also delete the top node (in your example
"MyUPnPServer", or the "category" node if you think of
services_discovery_AddItem) when the last child of it is being deleted.
(This functionality is necessary in a normal case when a SD module uses
strictly only the two SD functions to add and remove items)

So using services_discovery_RemoveItem( ) should work for you, but keeping
in mind that the top node has to always contain at least 1 item if you don't
want it to be removed.
