[Commentor] LC-263 Ian Jacobs [Comment] The first reference to "phase of work" is confusing. Does it mean "phase of this WG?" or "phase of this document"? Please clarify. It may be described in [Scope], but I think you need to provide a short summary of what "phasing" means or of what the phases are. [Commentor reply] yes [Working Group decision] 
We have expanded the consideration on phasing and have added a mention of the expected longevity of the document.
