XSLT fails with 'Content not allowed in prolog' when no 'Test XML' data present

[Don400]

Believe or not, it's true.  In the XSLT Source Text Input and Testing wizard, if you delete the test data from the text area in the Test XML tab, then the XSL transform will fail with the error 'Content not allowed in prolog' when the process executes.  I wasted a day and a half trying to figure this out - hope I've saved someone else the trouble.
