Known Subclasses:

A base class for metadata-related errors.

MetaErrors have a carrier attribute that should point to the MetaMixin item queried. Metadata propagation makes this a bit tricky, but we should at least try; for setMeta and addMeta, the top-level entry functions manipulate the carrier attributes for this purpose.

To yield useful error messages, leave carrier at its default None only when you really have no idea what the meta will end up on.
