Really - we don't allow for that? You sure?

I thought we did allow for this. If we don't, this seems like either policy or unrelated technical restriction, neither of which should affect design of this. This table should not be specific to the interwiki and "interlanguage" stuff at all - if you need another type of identifier that can be the same as one of another type, that'd just work with the current schema proposal, while I'd require changes if we put that primary index on si_key.
