Hi James,

So the draft currently specifies that only sos and children of sos 
are returned?  I'd missed that when I read and re-read the draft.  If 
so, that's fine with me, but maybe it can be made more clear.

For example, Section 4 says:

    The routing information in the location response consists of one or
    more service elements which is identified by a service name.  The
    service name is a URI and might contain a general emergency service
    urn such as urn:service:sos or might contain a specific service urn.

To me, this says that sos is just an example of a service that might 
be returned.

What might be better would be to modify my suggestion so that a 
<service> element can be included, and if not, the default is 'sos' 
and any children of 'sos'.
