Last I looked into it (mainly with interest for vim), few if any parsers/tooling exist for it outside of emacs; as I recall, people claimed that it apparently has sufficient (undocumented/poorly specified) quirks in the emacs implementation that 100% reproduction is difficult; similar to implementing vim-mode for editor plugins
In which case, its only as standardized as the one implementation; which is exactly how standardized markdown started with (the perl implementation)
