Metadata Generation

[Rod Widdowson]

We haven't really discussed this much and it is on my ever-increasing list
of things to get done for installation.

It did occur to me that idp.properties has all the information needed to do
simple metadata configuration:  entityID, tls and signing keys and
(eventually) back channel support and so it is the natural source for
information for a program to go between a template metadata file and an
example metadata file.

Does this make sense?  I'm sure we can do it in Ant (after all that’s what
V2 does), but given that the long term aim is to be able to drop entire
sections would XPATH be a better bet?  

If so, and if someone out there has the cycles, could they put together a
simple example?  I'd appreciate it - I am feeling very much under the gun
for the installer and I really do not want now to be the time I finally have
to learn xpath.

If not (to either or both) I'll just cobble up the ant thing.
