"""
This tests the case where a node is tagged with a type that apparently
comes from an extension that is known, but the type itself can't be found.
This could occur when a more recent version of an installed package
provides the new type, but an older version of the package is installed.
ASDF should still be able to open the file in this case, but it won't be
able to restore the type.
The bug that prompted this test results from attempting to load a schema
file that doesn't exist, which is why this test belongs in this file.
