I've talked to Love Hörnquist Åstrand (who can speak for himself
actually) - the heimdal lead - about SAML in the kdc (or any other
part of the code for that matter). He was mostly worried about
how the integration could happen safely. I think his position would
be similar to what a developer working on code never touched
by ASN.1 would be: this is a large piece of something I have no
control over and no way to audit.

So yes Scott, it is true that no SAML library supports XER out
of the box today but that is probably a minor problem compared
to figuring out how (say) something like heimdal could depend
on something like opensaml without creating an unmanageable
monster.

These are important things to figure out eventually but we
should probably keep the horse ahead of the cart for now and
concentrate on semantics.

    Cheers Leif
