I'm unqualified to review the Python but one thing in the specification doesn't look right.

> For XFAIL, if each expression is False then the test is expected to fail. As a special case "XFAIL: *" also expects the test to fail.


For XFAIL, if each expression is False then the test is expected to *pass*.  As a special case "XFAIL: *" expects the test to fail.
The xfail-expr-* tests get this right.
