5.2.1.b built-in derived types which allow empty content When you activate the Run Test trigger below you must see an 'xforms-valid' output for all the data types. If the data type does not accept empty content you will see an 'XFORMS-INVALID' output. An 'XFORMS-INVALID' output is a failure for this test case.
