I think I miss some things because there's no clear specification.
I still feel like your regexp could be lighter, or porbably split in several.

To me, the best idea in Markdown is to use shorter delimiters for
simplest/most common tags (like * * for bold, ** ** for italic, # for
title) : quicker to write, clearer to read (no big markup in simple
Images and links are both supported, as well as embedding raw HTML.
About the ilink / xlink functions, my approach would be to have only
one function for handling links, and use a custom href syntax. For
example : link=url would link to an absolute url, and link=p:page_name
would link to the named page. Like this, you can more easily extend
the syntax (img:image_name to link an image, file:file_name for files,
youtube:youtube_id, whatever). Btw, using a "protocol:" prefix makes
it look more like standard urls.
The goal (once again) is to split the regexp to have one for
retrieving tags, and then other regexps for interpreting them. Like
this, the regexps will likely be simpler, faster, and easier to
In general, using several simple regexp is better than using a single
big one, IMHO.

You're right I didn't get you could nest tags like this, or have @=b=@ tags.
Once again I think you should write a clear specification so that
you're sure you don't get conflicts or inconsistencies later, and you
know exactly what is an expected behaviour and what is a bug.
