Ah yes, I had forgotten about that paragraph. Sorry for the
misinformation.>>
This paragraph means absolutely nothing, let's quote it:
8 For nonboolean enumeration types, if the coding is not specified for the
type, then for each value of the type, the internal code shall be equal to
its position number.
But nowhere is internal code defined, and if you chase it around the RM,
you will find it is circular, and you can make it mean anything you want.
In no sense does this suggest anything about binary bit patterns.
