A syntax proposal: attributes for referenced links

["Choan C. Gálvez"]

Hi all.

I run an Spanish language blog where I usually link resources written in 
English, so I'd like to markup (some) links this way:

	<a href="http://daringfireball.net/projects/markdown/"
	hreflang="en">Markdown</a>

Would it be possible to extend the markdown syntax to allow this? I'm 
thinking about reusing the reference link syntax, this way:

	Blah blah [markdown][md] blah blah.
	
	[md]: http://daringfireball.net/projects/markdown/syntax "Syntax 
description" hreflang=en
	
This way, we could include any attribute in referenced links, for example:

	Blah blah [markdown][md] blah blah.
	
	[md]: http://daringfireball.net/projects/markdown/syntax "Syntax 
description" hreflang=en class=anything lang=en

(The lang attribute would translate both into lang="en" and xml:lang="en".)

What do you think about it?

Regards,
Choan

PS: Hope my "English" makes some sense today.
