Hi Folks, Is the following correct?
The -V limited option instructs Daffodil to check the input data for conformance to the XSD facets. The dfdl:checkConstraints also instructs Daffodil to check the input data for conformance to the XSD facets. So the -V limited option and dfdl:checkConstraints do the same thing, right? Not quite. Here's where they differ: Consider parsing input INP against an element ELMT that is inside an xs:choice. Case 1: The -V limited option is specified. If INP does not conform to ELMT's XSD facets, then parsing fails and Daffodil stops. Daffodil does not backup and try another branch of the xs:choice. Case 2: dfdl:checkConstraints is specified. If INP does not conform to ELMT's XSD facets, then Daffodil backs up and tries another branch of the xs:choice. Lesson Learned: (1) dfdl:checkConstraints is a superset in terms of behavior. That is, it does everything that the -V limited option does, plus more. (2) Forget the -V limited option. Just use dfdl:checkConstraints Do you agree? /Roger
