Scott Cantor commented on XERCESC-2188:
---------------------------------------
Scanning the code further, it does not appear the entity "stack" in the
ReaderMgr that these objects are pushed onto owns them or deletes them, so this
appears to leak to me. But that's not authoritative, just noting for any future
investigation.
