---------------------------------------
@Anderson, can you please attach a sample XSD document along with an XML
instance document, that illustrates the issue you're describing? That shall
help us debug, or suggest a workaround.
> 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 1.0 Structures, XML Schema 1.1 Structures
> Affects Versions: 2.9.0
> Reporter: Michael Glavassevich
> Priority: Minor
> Labels: gsoc, gsoc2014, mentor
>
> 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.
> With the introduction of XML Schema 1.1 support we would also need to
> consider how to improve this for the enhanced xs:all model groups.
