One way is through a filter. In the filter function you get an info
argument that contains the information you want. I hacked this together and
it does add a tooltip to the link, but it is not elegant or obvious, and it
does not do any checking for the type of link, whether an attr exists, etc.
The gist is that it looks like you can get the parent from the parse-tree
info, and get the attr_html info from that (which is a list of strings).
Then you have to modify the "data" in the filter function which is the
html. It is easy here to just replace the http://kitchingroup.cheme.cmu.edu
