I read nothing but good intent in your comment, so this is not me throwing stones, but one comment I would make is that I think using the term "prior art" - coming as it does from patent law - carries an overtone of "I am implying that you might have ripped off someone else's idea".

It's clear that this is not what you intended, but I think from the response from the creator, that was the tone that you accidentally conveyed.

Just a thought for the future :-).

it's all good, and please: if there is a better standard for me to follow, now is the time to implement it. You deserve the credit for bringing it to my attention, and the code base is pretty easy to navigate.
