Typos and confusing points

517 - Adaption to Adaptation
536 - mode to modes
558 - is valid application mode a view mode?
Because that doesn't seem obvious to me and it doesn't really seem to list any other modes? Just confused by that part.
598 - in to an, I realize you could have meant in, just wanted to make sure.
768 - as to a (not sure if that's jargon I don't understand or if it really does need to be changed.)
849 - ' to "
908 - "can" to "to" (again, not sure if that MUST has meaning I'm not understanding? I even looked at the keywords file RFC2119, still not positive.)
913 - added "a" before "string" and the algorithm had a path that ended in error so I thought "an error" should be a result, too?
947-949 - "When getting" doesn't really make sense, though I guess I see what you're getting. returns to return (unless I'm not understanding more jargon.)
1079 - pretty sure that shouldn't be "a manifests" if you're finding the media type for a manifest, so changed to manifest. Also, "a manifests" doesn't make sense.
