Yup, I remembered that -- their definition of simplified may differ from
mine ;-)

This from Sam Angove is informative:

Andrea Censi confirmed that [Maruku documents could be identified by
profiles][] and use:

"text/x-markdown; profile="

though there was some ensuing discussion about the legitimacy of
fragment identifiers for this purpose (or at least of parsing them,
instead of considering the URIs to be opaque).

If we could reach consensus about mime-type / profile, we could perhaps
submit them to Mozilla/Opera as recognised types to be rendered as
text/plain if no helper is installed?

[Maruku documents could be identified by profiles]:
