So it will likely get resolved when Discourse moves to it.
Are we migrating from markdown to this new thing, then?
It will still be markdown, just an actual spec.
From the CommonMark website:
##Why is CommonMark needed?
John Gruber’s canonical description of Markdown’s syntax does not specify the syntax unambiguously.
In the absence of a spec, early implementers consulted the original
Markdown.plcode to resolve these ambiguities. But
Markdown.plwas quite buggy, and gave manifestly bad results in many cases, so it was not a satisfactory replacement for a spec.
Markdown.plwas last updated December 17th, 2004.
Because there is no unambiguous spec, implementations have diverged considerably over the last 10 years. As a result, users are often surprised to find that a document that renders one way on one system (say, a GitHub wiki) renders differently on another (say, converting to docbook using Pandoc). To make matters worse, because nothing in Markdown counts as a “syntax error,” the divergence often isn’t discovered right away.
There’s no standard test suite for Markdown; MDTest is the closest thing we have. The only way to resolve Markdown ambiguities and inconsistencies is Babelmark, which compares the output of 20+ implementations of Markdown against each other to see if a consensus emerges.
We propose a standard, unambiguous syntax specification for Markdown, along with a suite of comprehensive tests to validate Markdown implementations against this specification. We believe this is necessary, even essential, for the future of Markdown.
That’s what we call CommonMark.
Rebaked OP and all appears to be working now!
