Re: Trouble validating XML w/ XSD.

This is the case where .NET 1.1 used to throw an error but .NET 2.0 now
throws only a warning.

For a root element node, if a schema matching the namespace if the element
is not found, then lax validation kicks in according to XSD spec. This
element is then validated according to the content model of xs:anyType,
which contains an xs:any with processContents=lax.

Since the declarations for 'thing' and 'thing1' are not found, it only
produces warnings, rather than errors, since this is how the semantics of
xs:any with processContents=lax work.

Note that in the invalid xml, your root element is in a namespace for which
you do not have a schema. If you remove the namespace declaration
xmlns="http://purl.org/dc/elements/1.1/"; and let <thing> be in the
targetNamespace of the schema, then you will see the errors.
