Make use of _allowMultipleMatches in FilteringParserDelegate #209
Description
Currently, it looks like that the _allowMultipleMatches attribute in FilteringGeneratorDelegate is not utilised (i.e. no value is assigned to this variable). Re. the documentation this attribute offers some useful functionality. So it would be nice, if it could be implemented properly.
