 5  	4 If there is an {attribute wildcard}, all of the following must be true:
 6  
 7  	4.1 The {base type definition} must also have one.
 8  
 9  	4.2 The complex type definition's {attribute wildcard}'s {namespace constraint} 
10  	must be a subset of the {base type definition}'s {attribute wildcard}'s {namespace 
11  	constraint}, as defined by Wildcard Subset (�3.10.6).
12  
13  	4.3 Unless the {base type definition} is the �ur-type definition�, the complex type 
14  	definition's {attribute wildcard}'s {process contents} must be identical to or stronger 
15  	than the {base type definition}'s {attribute wildcard}'s {process contents}, 
16  	where strict is stronger than lax is stronger than skip.
