Khaled Noaman resolved XERCESC-1333:
------------------------------------
Resolution: Won't Fix
This is the intended behavior. A unique particle attribution (UPA) check is
performed when a schema is processed and and the full schema validation feature
is enabled. The idea is to have the unique particle attribution check done only
once per grammar. Since a UPA check alters the state of the grammar (i.e.
changes the content model of complex types), we wanted to make sure that we
won't alter the state of the grammar when it's cached and used in multiple
threads.
