Description

Ran into this while working on a customer schema

Essentially if the default dfdl:lengthKind="implicit" and you attempt to use a dfdl:repType that involves uses string values for its enumeration, you will either get an error complaining that you cannot have an xs:string with lengthKind="implicit" without specifying a maxLength, OR for some unknown reason you can get a completely different usage error:
