Title: Guideline G2 to be reconsidered

Description: Guideline G2 [1], slated for Section 5.1 of the Guidelines document [2], reads: An assertion author should define policy assertions for behaviors that are relevant to compatibility tests, such as web service protocols that manifest on the wire. It seems to me that this good practice has been overtaken by events around Ignorable (and maybe even the closed/open world discussion of late). As editor, I dont feel comfortable adding it to the guidelines document without further clarification from the workgroup.
