What would happen if I suggested to this news group that Ada be
replaced by "a more compact notation" "useful for writing programs
when the use of ASIS and other tools are "not required."?

I admit that schema import statements are overly verbose. However,
standardization always has its costs. We have learned from Ada that
these costs are worthwhile. Schema maximizes readability and has range
checking and many other features very similar to Ada. In fact it its
possible to write schema following my style guide, FAKE ADA!
