I have this very basic element definition:

<xs:element name="elem01" dfdl:lengthKind="implicit" dfdl:length="5" type="xs:int"/>

When I specify this as the root of my test, I get the following error:

[info] - test_implicit_with_len *** FAILED ***
[info] java.lang.Exception: Schema Definition Error: MaxLength was asked
for when isSimpleType(true) and isPrimitiveType(true) Schema context:

however, maxLength can only be specified for xs:string and xs:hexBinary, and when I provide values for min and maxLength, I get errors that express such:
