LOL!
agree with you and for sure a lot of people don't even make the
difference between 110 and 112. From what I can tell, it's more of a use
for inter-emergency-services calls.
Yet it would be embarrassing if your SIP proxy would crash when it gets
such a crazy URN from some emancipated client.

AFAIK (but I could be wrong) URN are used by endpoints.
Real usage example:
1) The user is in danger since the fridge is empty.
2) He takes his "IMS-ready" phone and looks for "Emergency" menu.
3) There he selects: "urn:ietf:params:urn:emergeny:human:no-food"
4) The hyper-intelligent phone sends automatically a PUBLISH to all its
watchers containing a header "Accept: Burger" and body:
<dm:person id="hyper-cool-ietf-ims-oma-phone">
<rpid:activities>
<rpid:hungry/>
</rpid:activities>
<dm:note>Food please</dm:note>
</dm:person>
5) The phone also makes a call to all the proxies close to it with URI:
"urn:ietf:params:urn:emergeny:human:no-food"
6) The proxy translates that URI into "sip:1...@legacy_gw_ip" and
routes the
call.
7) When the emergency service answers the call, a voice + video +
MSRP session
is started. Nothing works due to NAT.
8) At the same time some IETF member is writting a draft about "urns"
uri called:
"draft-ietf-i-am-cool-because-i-write-drafts-secure-urn.txt"
