Hi,
Is the new SessionInitiator functionality of the SP documented anywhere 
yet?  If not - do I understand correctly that this should allow runtime 
determination (via lazy sessions, etc) of which WAYF or direct IdP the 
user goes off to to establish their session?  Could someone supply a 
quick usage example (query parameter string, e tc)?  Between the 
shibboleth.xml embedded comments and looking at the code, I don't think 
I understand exactly how it's supposed to work.

Where the comments say:

Automatic session setup will use the default or first
element (or requestSessionWith can specify a specific id to use). Lazy 
sessions
can be started with any initiator.

How does one explicitly invoke a specific initiator (other than the 
default), for example with a lazy session?  requestSessionWith? If so, 
how, where? That's a URL query parameter?  Does it make a difference 
whether sessions are lazy or not?   I tried playing around with it, but 
I keep getting an error that I need a wayfURL property (which I have), 
so I'm obviously doing something wrong...

Finally, what is the purpose/meaning of the SessionInitiator Location 
attribute?  That's not obvious to me.

Like I said, if this is documented somewhere, just point me there.  I 
looked in the deploy guide and the wiki, but maybe I'm just missing it.

Thanks,
Brent
