Michael Glavassevich resolved XERCESJ-206.
------------------------------------------
Resolution: Fixed
I've just committed an improvement to code in SVN which covers a number of
common cases. We now build a representation of large minOccurs/maxOccurs in
constant time and memory (which uses a counter during validation) for element
and wildcard particles when each model group particle in the content model:
* has minOccurs/maxOccurs == 1; or
* contains only one element/wildcard particle with minOccurs/maxOccurs == 1
Handling sequences, choices and nested minOccurs/maxOccurs is somewhat tricker.
We would need a more general solution than the one implemented for elements
and wildcards to process those gracefully. I've opened a new JIRA issue [1]
for tracking that.
