Re:  When maxOccurs=1 means an unbounded number of occurrences

I would disagree only with your initial interpretation: I think minOccurs=1 - I think 'exactly' trumps 'MAY'.

It struck me as being thoroughly ambiguous, but perhaps if we had more context it would become more clear.

The RFC says that Name must occur *1 times, where *1 is defined as “Exactly one instance MAY be present.” I interpret that to mean minOccurs=0 and maxOccurs=1.
