The "realm" module always reads the list of realms from "proxy.conf", 
honouring the special realms DEFAULT and NULL (I'm ignoring the regexp 
syntax stuff here).

Doing it manually with "unlang" lets you specify the mapping from Realm 
to Proxy-To-Realm yourself, and you can be more flexible and explicit 
about it.

i.e. with "suffix" you might have:

user at example.com
   Realm = DEFAULT
   Proxy-To-Realm = DEFAULT

...versus unlang you might set:

user at example.com
   Realm = example.com
   Proxy-To-Realm = SOMEPROVIDER

Basically, using unlang is a bit more configurable, which is 
particularly useful in a roaming federation like eduroam.
