[Commentor] LC-292 Ian Jacobs [Comment] That last sentence is a good place to start for this entire document. But there are other sentences that talk about One Web that might be pithier. I think you can drop "as is practical" and all similar qualifiers in favor of a section in the document about the general authoring context. [Commentor reply] yes [Working Group decision] 
We think "as is practical" does convey the message that the Working Group has in mind; note that this document is informative and aims at providing guidance to authors, not imposing very specific rules - that will be done in the mobileOK trustmark.
