Thanks for reminding me about this. You're right about the terminology.

I think, in "document order" provided the items in the 2.0 sequence
represent nodes of the XML document. In case, the items of the sequence are
atomic values, then the term "document order" in this context doesn't make
sense, since atomic values have their own order (which is not "document
order").
