Major Description
When validation is limited, the length facet isn't enforced during validation and it requires the use of maxlength and minlength facets for enforcement.
Possible solution: Inside daffodil really there should be use of maxLength and minLength values in the DSOM model, but those should be populated regardless of whether maxLength and minLength are specified separately, or only length is specified.
It should also test to ensure you don't specify both length and either of maxLength/minLength as distinct values.
