Section 8 says:
none - suggestion below is an addition
It should say:
Add a new paragraph: Note that registered Relation Names are required to be lower-case ASCII letters.
This is not important, but a useful placeholder for any future revision.
One can determine the above by tracing back through the ABNF to RFC 2616 and examine the LOALPHA production there. But, to prevent confusion, an "Internationalization Considerations" section should probably call out ASCII restrictions explicitly. One could, as an alternative, include that information under "IANA Considerations" for new registrations (Section 6.2.1 of the present version), but I believe it should be explicitly noted somewhere in this document.
