First, RFC 6761 is silent about the characteristics of the documentation to include in such a draft. RFC 6761 is very specific about "in each of the seven categories below, what special treatment, if any, is to be applied" but never mandated a specific type of external references. Second, I much prefer an URL (a few seconds after, I have the document and I can read it) to... (incoming troll) a DOI or other kind of reference that I may or may not be able to dereference.
