XForms 1.1 test suite issues

I've uncovered the following validation errors in the XForms 1.1 test suites in the process of producing and testing the Relax NG XHTML+XForms integration.  

I have recommendations for most, but a few require special examination:
- There are two tests that I believe are no longer used, and are likely present but not referenced.  
- There is a test with binding exceptions that I don't understand. 
- There is a test using choices with no contained items that I believe we should consider separately.

Fetch the test suite from http://www.w3.org/MarkUp/Forms/Test/XForms1.1/Edition1/zip/TestCases11.zip and save this file in the same directory.  Unzip both and the links from this document will take you to the test cases.
