I'm sorry but the behavior of final & block attributes is nonesensical
and rarely "needed" especially when one considers that few people even
within the W3C XML Schema working group can clearly spell out tell the
difference between final & block on element declarations vs. complex
type definitions. 

Identical units which test in an identical fashion will not behave in an
identical fashion in the field.
