+	4 If there is an {attribute wildcard}, all of the following must be true:
+
+	4.1 The {base type definition} must also have one.
+
+	4.2 The complex type definition's {attribute wildcard}'s {namespace constraint} 
+	must be a subset of the {base type definition}'s {attribute wildcard}'s {namespace 
+	constraint}, as defined by Wildcard Subset (§3.10.6).
+
+	4.3 Unless the {base type definition} is the ·ur-type definition·, the complex type 
+	definition's {attribute wildcard}'s {process contents} must be identical to or stronger 
+	than the {base type definition}'s {attribute wildcard}'s {process contents}, 
+	where strict is stronger than lax is stronger than skip.
