Just an FYI, but the section separator that Alan mentioned is actually part of YAML. In fact, IIRC without it the YAML parser would consider it an invalid document. I guess the point is that what marks the meta-data could be dependent on what format is used for meta-data. That might be hard to define in a Markdown spec if we leave it open for any meta-data format. > Definition lists > The fact that including more than one definition for a given term is an > uncommon requirement should not preclude such use cases from being > accommodated.

In fact, the HTML5 spec [1] calls `<dl>` a "description list" which expands beyond definitions. It states: "Name-value groups may be terms and definitions, metadata topics and values, questions and answers, or any other groups of name-value data." And then proceeds to provide examples, one of which specifically provides two terms for a value. I don't see any reason why a markdown variant wouldn't support all the same use cases.
