What's the use case?  More generally, in WD3 at least, there are no examples of alternateOf or specializationOf in use (with or without attributes).

If we want to make things really uniform, we could identify a common "template" for all of the record forms

record(id, blah, blah, ... , attrs)

Most of the rules in ProvRDF have this form already.
