Would I convert a string input to a key, or should I only accept a key
as a valid id? The latter seems more convenient but I imagine would
break backward compatibility.

So cross voice spanners should only work if the context to share
information is specified, right? If the context is not specified and
there is no default, the spanner id would only be used within the same
voice and not made known to any other contexts.
