i stole some code from opensips and normalized the rls-services uri.
after that, the match was found:

that, however, didn't get me much further.  next i got error:

May  1 22:15:45 siika /usr/sbin/pres-serv[29546]: ERROR: rls [notify.c:1171]: resource list 'http%3A//192.98.102.10%3A8080/xcap-root/resource-lists/users/sip%3Ajh%40test.tutpro.com/index/%7E%7E/resource-lists/list%5B%40name%3D%22sipsimple_presence_rls%22%5D' is unidentifiable

the reason this time is escaped http uri, because uri scheme comparison does
not take into account escaped : char.  in rls/notify.c:

#define HTTP_PREFIX		"http://"
#define HTTP_PREFIX_LEN		7
...
if(strncmp(uri, HTTP_PREFIX, HTTP_PREFIX_LEN) == 0)

looks like there is lots of work to be done on rls module before these
things are sorted out.
