Books example has incorrect transformation SQL in XML document model

I imported the Books Project into my workspace and found the XML document model had errors, Checking, I found the transformation SQL referenced the wrong models. For example,
SELECT
Books_Oracle.AUTHORS.LASTNAME AS author
FROM
Books_SQLServer.BOOK_AUTHORS, Books_Oracle.AUTHORS
WHERE
("input".isbn = Books_SQLServer.BOOK_AUTHORS.ISBN) AND (Books_SQLServer.BOOK_AUTHORS.AUTHOR_ID = Books_Oracle.AUTHORS.AUTHOR_ID)

should reference Books_SourceA and Books_SourceB rather than Books_SQLServer and Books_Oracle.
