Patch by Sjoerd Mullender to placate /F:
Fix leaking of instances by removing the elements variable that we created on closing the parser. The elements variable is now created in the reset() method, so that the sequence close(); reset(); ... works. Also, add the name of the entity reference that wasn't found to the error message.
