+     <note>
+      Implemented improvements in the processing of large minOccurs/maxOccurs on 
+      element/wildcard particles which once caused OutOfMemoryErrors to occur during
+      validation. Note that an OutOfMemoryError may still occur if the minOccurs/maxOccurs
+      are nested or appear on a sequence or choice model group.

+    <update>
+     <note>
+      Improved the algorithm for checking the Unique Particle Attribution constraint so that it 
+      no longer causes an OutOfMemoryError for content models with large maxOccurs values. Note that 
+      this only applies to the checking of schema validity. An OutOfMemoryError may still occur if 
+      the schema contains large maxOccurs and is used to validate an instance document.
