OK, one more, again a repeat of an old request.

Pandoc Markdown has this incredibly easy way to specify html attributes (
http://pandoc.org/README.html#header-identifiers):

----
# My Header {#myid .class1 .class2}
----

I find this much easier to read, write, and maintain than the org-mode
equivalent:

#+ATTR_HTML: :id myid :class class1 class2
* My Header

I would love to have something like the pandoc syntax available within
org.  What do other people think, and how hard would this be to implement?
