MDEE (Markdown) & MDSVX (Svelte + Markdown)

Sublime Text Language Syntax forked from Markdown Extended, with extended list of syntaxes, and support for adding CommonMark / Attribute Strings to the Language Identifier. Languages have been updated to reflect languages in 2026, for use in Fenced Code Blocks. A second language wrapper MDSV is for use with MDsveX, for Svelte written with Markdown. ESLint configurations for linting and LSP can be found at Sublime DX.
