Subject:Performance problems with xsd all groups.

I've been using the Xerces-J 1.2.1 parser for validation using schemas. When using xsd all groups in xsd files, if the number of elements in the all group is 5 or less, Xerces-J validates instance documents efficiently. When the number of elements in the all group is 6 or more, performance goes from seconds to validate instance documents to minutes. Some test cases generate java.lang.OutOfMemoryError exceptions after running for a minute or two.
