I'm struggling to understand the structure of this contraint. 

It starts with a definition

"sub is a wildcard subset of super  if and only if  one of the following is

and then continues:

"And all of the following must be true..."

Is this part of the definition? (if so, why "must"?)

I would expect the structure here to be

... all of the following are true:

1 One of the following is true:
2 Each QName member of super.{disallowed names} is not allowed by sub..
3 If super.{disallowed names} contains defined, then...
4 If super.{disallowed names} contains sibling, then...

(Note also the use of apostrophe rather than dot in the last clause)
