Editor of urn:ietf:id:draft-snell-atompub-bidi-03 could either: 
- drop the draft and use its:dir instead of atom:dir
- add http://www.w3.org/TR/its/#directionality as Normative references
- add http://www.w3.org/TR/its/#directionality as Informative Reference 
- add http://www.w3.org/International/articles/inline-bidi-markup/ as 
 Informative Reference 
- let the draft without reference to ITS
