Mike Beckerle commented on DAFFODIL-2596:
-----------------------------------------
We ran into a related problem. Our data is binary with 1-bit alignment.
For our enums which have binary repTypes, but strings as the enumeration
values, not only did we need to put in dfdl:lengthKind='delimited' but
dfdl:alignment="8" in our format because Daffodil thinks somehow the string is
being used for representation and issues errors about the characters of a
US-ASCII string not being 8-bit aligned.
Basically, some of this checking in Daffodil pre-dates the introduction of
dfdlx:repType, so does not treat the string as just a computed element.
> lengthKind property is not inherited for types with dfdlx:repType

> 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:
