Parser mistakenly throws SAXParseException with message
  "Current configuration of the parser doesn't allow a maxOccurs
   attribute value to be set greater than the value 30."

while parsing document with schema which defines maxOccurs='11'. The
SecureProcessing object with MaxOccurNodeLimit=30 is set for the parser.
The same effect is observed for some other pairs (MaxOccurNodeLimit, maxOccurs)
and sometimes parser processes valid combinations correctly.

The sample below contains document where element <e2/> occurs 4 times and it
is parsed with following (MaxOccurNodeLimit, maxOccurs) values :

   not set, 3 OK: schema constraint violation detected
2, 3 OK: (maxOccurs > MaxOccurNodeLimit) detected
9, 3 OK: schema constraint violation detected
9, 4 wrong SPE("configuration doesn't allow a maxOccurs > 9")
9, 5 wrong SPE("configuration doesn't allow a maxOccurs > 9")
30, 5 OK: parse without errors
30, 11 wrong SPE("configuration doesn't allow a maxOccurs > 30")

The log is provided below.

The bug affects new tests in JCK 1.5 (not yet integrated):
  api/javax_xml/SecureProcessing/index.html#MaxOccurNodeLimit[SetMNL_502]
  api/javax_xml/SecureProcessing/index.html#MaxOccurNodeLimit[SetMNL_552]

The bug found in the JDK 1.5.0-beta-b32.
