How about: "The following tags are non-standard and will likely be ignored by most verifiers"?

Some of Tony's examples such as "h=rsa-sha1" can certainly be reported as "invalid" as they are standardized tags with illegal values (i.e., the legal values are enumerated).

Alas, no.  And it would be difficult, I think, to try to corral people into using one in general (though the audience is currently pretty small so for now it's a practical idea).
