 Replying to [comment:3 mikeschinkel]:
 > While I am normally not the one to disagree with a feature request this
 does strike me as violating a lot of the assumptions of attributes in
 HTML/XHTML after which shortcodes are at least partially modeled. I fear
 potential unintended consequences (read: "hard to squash bugs") if this
 were enabled.

 Indeed it feels unnatural, but in general a plain regex don't behave
 exactly like normal HTML tags, like in the impossibility of embed a same
 shortcode inside the content of itself, as far as I know. In an attribute
 is possible, thought.

 I was trying to replicate the usage of MediaWiki templates (or
 "transclusion"), which allow to create snippets with custom snippets and
 markup inside the attributes and even with parse functions (which can
 already be done with PHP).
 [http://en.wikipedia.org/w/index.php?title=D-Sides&action=edit An example,
 although a bit extreme]. I was trying to update an old plugin with a
 similar function, but since shortcodes is already the most similar
 approach I thought it could fit.
