+ | DESCRIPTION |
+ If my base type uses locally declared elements, an attempt to restrict that
+ type gets a rcase-Recurse.2 error. (I'm not completely sure that this is a
+ bug, since the spec's language on restrictions is so difficult. But the XML
+ Schema Primer's example of restricted types uses local element declarations.)
+
+ Here is a schema that demonstrates the problem. It has equivalent restricted
+ types, one with a base type built of locally declared elements and the other
+ with a base type built of globally declared elements:
