I created a separate bug for this so DFDL-483 doesn't get too hard to follow.

I wrote a test that uses a sequence with minOccurs = 3 and maxOccurs = unbounded.

[info] Test edu.illinois.ncsa.daffodil.section02.validation_errors.TestValidationErrDebug.test_facetCombos_fail_limited_02 started
Validation Succeeded!
2013-07-02 06:59:54:321 edu.illinois.ncsa.daffodil.tdml.ParserTestCase Error[Validation Error: element.e occurred '7' times when it was expected to be a minimum of '3' and a maximum of '-1' times.
Schema context: Some(element.arrayCombo). Location line 22 column 353 in file:/tmp/daffodil_tmp_3337200428269477730.dfdl.xsd. Data Context: byte 14

based on the schema I have an acceptable number of elements, but it seems to think I have too many because maxOccurs unbounded seems to be translated to -1.

see tests facetCombos_fail_limited_02 and facetCombos_fail_on_02 in the following files:
