I'm just saying it's not pre-fetching. If you want to use the EDS, you can't use MDQ, it simply isn't compatible.

There are lots of ways to do discovery and all of them are bad. As a project, it's fair to say we gave up. I would personally just use Seamless Access if the list was huge and just create a simple UI myself if the list was small.

You could of course just build an XSLT that consumes the metadata aggregate out of band and produces the JSON for the EDS, or some other driver of a discovery UI. Ian actually threw together an MDA pipeline example that does it, we used it very briefly on shibboleth.net before we got out of the federated app business.
