We use the Jena parser, so yes.

Once we get it from the parser, we keep it as it was given to us. We
don't process XMLLiterals, and we only canonicalize data types that we
want to process.

It wouldn't affect us, unless we started processing XML. In that case,
I can say that storing non-canonical forms is undesirable.

This merits a similar response to 4.

No and no.
