FWIW, I would have said it as eiether:

"To be a conforming *schema document*, maxOccurs must be greater than or equal
to minOccurs".

Or in the conformance section:  "To a conforming *schema document* must obey
all the individual contraints on schema documents", and (presumably elsewhere)
"Schema Document Constraint: maxOccurs MUST BE greater than or equal to
minOccurs"

I thought our status quo was pretty close in spirit to that second approach.  

In short, I don't want to say that "documents conform to our Recommendation". 
I think I do want to say that a particular document does (or doesn't) conform
to our rules for *schema documents*, or more briefly "this is/isn't a
conforming *schema document*".

Question:  don't you have to go beyond saying that "they must be enforced". 
Don't you have to say "for a document to meet the definition of *schema
document*, or if you prefer, to be a conforming *schema document*, there must
be no errors such as the one mentioned above?  How would you make such a
connection, or would you?  I'm really reluctant to lose the notion that to be a
(termref) *schema document*, you must obey rules like this.  Thanks.
