> That data can be described with the following schema:
> {code:xsd}
> <xs:element name="D"type="xs:string"
>     dfdl:lengthUnits="characters"
>     dfdl:lengthKind="prefixed"
>     dfdl:prefixLengthType="D-type"
>     dfdl:prefixIncludesPrefixLength="no"/>
> <xs:simpleType name="D-type"
>     dfdl:lengthKind="explicit"
>     dfdl:length="1"> 
>   <xs:restrictionbase="xs:integer"/>
> </xs:simpleType>
> {code}
> DAFFODIL-114 added support for lengthKind="characters", but upon testing it looks like it created an Assert.invariant if the lengthKind="characters" for a prefixed length element. On 2.4.0, that invariant doesn't happen, but the lenght is calculated incorrectly. In 2.4.0, it only parses a single character, even though the prefix length is 3.
> Also see related DAFFODIL-2029, which is to add support for unparsing lengthKind="characters" prefixed length elements.
> If we don't support this yet, we might just want to make it a notYetImplemented error.
