I'm not sure how these custom styles work so bruno should confirm this.
The current code works for any tag/attribute combination that has has
text inside the tags; for the special case <img .../> there is a
workaround. If you're going to add things like <input .../> (is this
even possible?) then the changes to that tag will not be visible. The
tag will be in the page if it is part of the most recent document. 
I could make the <img ../> workaround more general for all such empty
tags if there is a need for that.
