True, but I hate tools that give boat-loads of warnings without an
efficient way to suppress them. The 1st attribute domain style greatly
simplified the task that a user might have of turning off warnings for
legal but irrelevant attributes. One could turn off all warnings but then
we lose the attribute-checking capability.
