Regarding XML literals, I have one request to make to the WG, in its deliberations on this topic. Speaking as the semantics editor, I really do not give a damn what XML literal values are defined to actually BE. What I do care about, a lot, is this: whatever they are defined to be, that the lexical-to-value mapping from the legal lexical forms is precisely and unambiguously 1:1. We have already canonicalized the lexical forms about as strongly as the combined forces of XML and RDF are able to canonicalize them; the operational point of doing this is so that an RDF engine can compare equality of literal values by comparing identity of lexical form, and we don't have to have special inference rules which substitute different but co-referring XML forms one for another in all possible ways. If we lose this 1:1 nature of the mapping, then we might as well not have bothered to have a canonicalized lexical form. SO please don't do anything that runs a risk of losing that property. I do not know if having lexical-to-value be UTF-8 encoding does so or not. I would rather not have to know, to be honest.
