Mike 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.

(The issue of nil representation being empty string requires %ES; or %WSP*; alone. (The latter having been omitted in now two identified places.)
