I would avoid this wording. I would instead say:
It's a flavor of markdown. The flavor is heavily documented. The flavor's name is "Standard Markdown".
My problem with the name "Standard Markdown" is I don't think it's going to be clear enough, I think people will think it's the same thing as Markdown (which it's not), under the theory that "non-standard" would have an obviously different name such as "Lisp Markdown" or "Japanese Markdown".
If they had used a word other than "Markdown" I wouldn't have a single problem, I would cheer them on.
I don't see a real benefit in this name to anyone, but I see serious downsides.
That's certainly an unbiased translation :rolls eyes:. If you want to have a good-faith debate, you should avoid tendentious re-writes of your interlocutor's arguments.
You clearly don't like his position.
Be he has explicitly chosen not to make a specification, he's had years and numerous requests. From what I've seen/heard John Gruber likes that it isn't formalized with a spec.
So if a group of people, especially a large group with 10s of millions of users (at a minimum) decides to write a spec and name it "Markdown" over Gruber's wishes it sounds like trying to take ownership from him.
My phrase was glib, but I don't think it's that far off from many of the comments expressed here.
The reasons that he didn't write a spec after requests is very likely post-hoc rationalisation, behind the simple reason that writing a spec is not a fun task.
