I think is the updated Experience document 4 erratum 5.32 ...

5.32 Section 9.3.2.1 https://redmine.ogf.org/issues/309

Update bullet 1 which says “1. nil representation (if %ES; is a literal nil value).” to say “1. nil representation (if %ES; or %WSP*; on its own is a literal nil value).”
 
Also Section 9.2.5  the phrase

        “… can be a zero-length representation if dfdl:nilValue is "%ES;",...”

should be replaced with  

        "... can be a zero-length representation if dfdl:nilValue is a list containing either %ES; alone, or %WSP*; alone, and ...."



I prefer the following for the 9.2.5 update, as dfdl:nilValue does not have to be a list ...

        "... can be a zero-length representation if dfdl:nilValue contains %ES; or %WSP*; on its own as a literal nil value, and ...."

or re-use the phrase from 9.3.2.1 ...

        "... can be a zero-length representation if %ES; or %WSP*; on its own is a literal nil value, and ...."


Note that the DFDL String Literal grammar in 6.3.1.2 ensures that if %ES; appears in a string literal, it is the only content of that string literal, so no need to qualify it further.

Per recent email threads - another place was found that needed the same change as detailed in Erratum 5.32, so that was just augmented to also specify the same change.
(The issue of nil representation being empty string requires %ES; or %WSP*; alone. (The latter having been omitted in now two identified places.)
