[Commentor] LC-288 Ian Jacobs [Comment] * This can be a dangerous point if not worded carefully. See the relatedprinciple in Webarch: " Agents that recover from error by making a choice without the user's consent are not acting on the user's behalf." I realize that in this context one may not always be interacting directly with the user. But "silently recovering from error" is one of the things that I believe the TAG feels strongly is a bad thing. [Commentor reply] yes [Working Group decision] 
The "silently recovering from error" point is relevant to user agent requirements which is out of scope. We believe the text already addresses the issues you've raised.
