yw - it still seems like some xml schema issue, namely PSVI handling in
XmlSchemaValidatingReader (ok, less than 0.1% of people understand it).
In case you don't mind patching EF, here is mine that goes beyond that
issue.

Many thanks to Atsushi Eno for a solution for previous defect in
System.Xml.
But there are new issues with EF. I tried to create simplest console
application (file Test.zip attached to this letter, contains
MonoDevelop project), it fails with following exception:
System.ArgumentException: An element with the same key already exists
in the dictionary.

Honestly, I'm going to investigate and probably rewrite my code to
NHibernate, but if this sample project will be useful for someone who
will try to make support of Entity Framework on Mono better, I would
be glad to know it.
With best regards,
