Yes, I'd forgotten about the label ("label" is the LaTeX name for what
you're calling "tag" here).

Yup, this is the slightly trickier part. A sketch of the solution, we need
to:
- generate a local anchor element for the labeled output. That's the
easier part, it would be the job of the displayed output from this
hypothetical Figure() object.
It needs to wrap the output in `<a name=label>... </a>`.
- For markdown referencing, you simply do [link text](#label).
- The problem would be latex conversion: by default, the above is converted
to
\protect\hyperlink{label}{link text}
where as you want a \ref{label} call instead.
- You also want this to generate the
Internal cross-referencing is one of Markdown's main weaknesses for complex
more document-oriented workflows that aren't purely HTML oriented.
Markdown is really a thin wrapper around HTML, so it doesn't expose the
rich labeling/referencing semantics of rST or LaTeX.
I didn't say this was a done deal, and there might be some tricky edges to
it :)
