[Commentor] LC-290 Ian Jacobs [Comment] * Below you say something more interesting, which I paraphrase as "It's ok to not follow some of the other best practices in this document when you need to work around errors." That's a big gate and you should strive to narrow it. Furthermore, you seem to define conformance below "then content providers must comply..." Does that statement belong in 5.1.3.1 or is it a general statement that belongs in a conformance section? [Working Group decision] We decided to keep the best practice as is, but we have added text to the default delivery context to mention that no get-out clauses apply in the default delivery context. [Commentor reply] 
yes
