xml validation performance bad when maxOccurs is big
----------------------------------------------------
Key: XERCESJ-1091
URL: http://issues.apache.org/jira/browse/XERCESJ-1091
Project: Xerces2-J
Type: Improvement
Components: SAX
Versions: 2.0.0 [beta 4]
Environment: Solaris 9
Reporter: yiguang hu
For the following schema, the validation of a XML file (with only one record)
against this schema took several minutes. But if the maxOccurs="9999" change
to maxOccurs="999", the validation takes 2 second. I was able to get around it
by using "unbounded". Don't understand why 9999 could cause such a big
differnce for validation.
