According to the production rules for the prolog in XML 1.0 spec, no whitespace nodes are allowed in front of the XML declaration. Appendix 7, which is non-normative, seems to allow byte order mark as first character.

If a BOM is present: Is it part of the document and should it be counted as a character when we get the character offsets? Or is it only only a bit of information for the parser?

How to handle it? According to RFC 5147, sec. 2.1.2, BOM should not be counted.
