-----------------------------------------------
Chris, you should try out the current code in SVN. For a number of common
cases it will now handle large minOccurs/maxOccurs in constant space and time.
> Poor performance / OutOfMemoryError for sequences, choices and nested with
large minOccurs/maxOccurs

> Key: XERCESJ-1227
> URL: https://issues.apache.org/jira/browse/XERCESJ-1227
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema Structures
> Affects Versions: 2.9.0
> Reporter: Michael Glavassevich
> Priority: Minor
>
> We now handle large minOccurs/maxOccurs on element/wildcard particles more
gracefully by creating a compact representation in the DFA and using counters
to check the occurence constraints, however we will still fully expand the
content model for minOccurs/maxOccurs on sequences and choices which could
still lead to an OutOfMemoryError or very poor performance (i.e. could still
take several minutes to build the DFA). Sequences, choices and nested
minOccurs/maxOccurs are somewhat tricker to handle. We would need a more
general solution than the one implemented for elements and wildcards to improve
those.
