Thanks Yankee.
Yes, we have been discussing the phrases "in accordance with" and "according to" in specific contexts, namely, when talking about doing something you're supposed to be doing, have agreed to do, or are doing. We have been talking about what forms and combinations are appropriate in that context.
Examples of "In accordance to..." have been found, although they do not seem natural at all to me and I would never use that phrase, always using "In accordance with" myself.
However, I will continue to say that "in according with" or "in according to" -- keeping with the subject of this thread until this other example you introduced -- are not used.
Yes, when other definitions of a word are used, other combinations are possible.
