----------------------------------------
Summary: Need validation of tunable values
Key: DAFFODIL-2432
URL: https://issues.apache.org/jira/browse/DAFFODIL-2432
Project: Daffodil
Issue Type: Bug
Components: API
Reporter: Steve Lawrence
The TunableGenerator.scala file use the dafext.xsd file to generate code to
parse tunables. This handles things like correctly converting types or handling
default values. Unfortunately, it only does type validation, nothing about
value validation (e.g. value must be positive). This means we must either add
custom validation code for tunable values long after they have been set, which
can possibly lead to confusion, or we don't do any validation at all, which can
lead to undefined behavior.
Instead, we should add xs:restriction's to the tunables list in dafext.xsd, and
have the TunableGenerator create code to validate based on these restrictions.
We don't necessarily need to support all XSD restrictions--probably
min/maxInclusive is suffiicient.
