RE: [XML Schema 1.1] Multiple <alternative> elements apply ... which one wins?

See section 3.3.4.1:

[Definition:]   Given a Type Table T and an element information item E, T
conditionally selects a type S for E in the following way. The {test}
expressions in T's {alternatives} are evaluated, in order, until one of the
Type Alternatives .successfully selects. a type definition for E, or until
all have been tried without success.

So the answer is: the first one.
