You are right. Apparently some of the numbering got messed up in the final document for the terminals in the grammar. (I just checked but all of the non-terminal seem to be consistent with the XQuery document). Sorry for that mistake, we will try to fix that in the next version of the document. Yes, you should rely on the appendix for the normalized core grammar. In any case, this is the only place in the Formal Semantics document that describes the core grammar completely. The 'Core grammar' subsections in the rest of the document are not complete and are only a reminder for the reader.
