Revising test 6.1.6.a for correctness

Dear Forms WG,

Test 6.1.6.a tests the constraint model item property.  However, the 
expression in the constraint does not produce the desired results 
expressed in the test without adding an invocation of the number() 
function to ensure numeric comparison.  We do not know how all other 
implementations could pass this test without amending that expression, so 
we suspect this is what happened and that the revision simply hasn't made 
it back to the core W3C test suite.  It is the case for Ubiquity XForms 
that our reported pass of this test is based on a revised test in our test 
framework, which is attached here for reference in amending the W3C test 
suite.



Thanks,
