> DPath only allows predicates as integer expressions to index arrays. With an invalid test, a Schema Definition Error is thrown but it seems to be trying to parse the predicate as a path and giving the error message that the element was not found.

> [error] Test edu.illinois.ncsa.daffodil.section23.dfdl_expressions.TestDFDLExpressionsDebug.test_predicate_02 failed:
