Removed scxml/@profile and scxml/@id properties from test documents that were breaking validation.
Removed test initial3, as having an initial state child of scxml is not compliant with the current spec.
Removed initial children of scxml which is not valid.
Fixed conflicting datamodel and state ids, which were breaking validation.
Added missing transition element children to history states. All tests now validate, and pass when run against SCION.
Fixed test for send/@delayexpr to return expression in CSS time (specifically with 'ms' appended).
Eliminated calls to SCION-specific functions getData and setData, and replaced with simple references and assignments.
Removed tests for assign-next-small-step from master which test SCION-specific features.
