My remark about syntax was orthogonal to your patch. I was just pointing
out you used a wrong example. Eric Schulte will know better than me
about your patch.

It would be better, indeed.

Of course not. With:
#+attr_html: alt="big image" width="100%"
file:123.png
(org-element-property :attr_html (org-element-at-point)) with point at
"file:..." will return ("alt=\"big image\" width=\"100%\"") while on the
following example:
#+attr_html: alt="big image" width="100%"
file:123.png
it will return nil.

Babel behaviour is already slightly different from Elements's. In the
long run it will be necessary to correct this.

You may have a look at the comments at the start of org-elements.el. At
some point, I will have to write an Info doc about this library, unless
I postpone it until the end of time.
