Was that a requirement ?  The VAX Ada Version 2.0 manual I have from
DEC shows a little pentagon-shaped logo saying "Validated Ada" in the
middle and cites ANSI/MIL-STD 1815A as determined by the AJPO under
its current testing procedures.

But Section 13.5 after Paragraph 7 has vendor-specific (blue) text
saying "In VAX Ada, the simple name must be the name of an object."
