Yes. I have code to do that. There was a problem with "standard" and
"standardtype"
which will clash if abbrevitions are used ("standardtype" is renamed
"knowntype").
Assuming nobody had "standardtype" shortened to "standard" it should be OK.

The existing code had to be cleaned up for acdvalid to report correctly,
but now the ACD files are cleaned we can add the old "required" and
"optional"
attributes back as aliases ... but for a limited time. They will be gone
by release 3.0.0.
