Complex types can have default values? Are you sure? My reading of the
spec (the definition of {value constraint} in section 3.3.2) is anything
but definitive, but I think it means that only simple element types can
have defaults. On the other hand "Schema Information Set Contribution:
Element Default Value" in section 3.3.5 seems to hint that complex types
can have defaults. Must have forgotten my schema spec decoder ring today

Do you mean syntax/structure of the instance? I'm not sure I follow.
