[DFDL-WG] ES in delimiters

Steve Lawrence from the Daffodil project has observed that we're not particularly consistent about delimiters and the %ES; entity. We allow WSP* with caveat that you can't have initiatedContent, but we disallow ES. There is a use case for optional delimiters e.g., initator="%CR;%LF; %ES;" meaning absorb and discard an optional CRLF. Without %ES we end up having to model this syntax as an optional hidden element.
