After a bit more
testing, the code doesn't quite work. If there is an 'emphasis' tag inside a
'link', that text is not generated as a title. For instance, I have
citations with 'et al' in an emphasis, and the generated title has the text
of the citation except for 'et al'. I'll need to find out how to select the
content of a link and its children.
While not an expert on
accessibility, I feel it is a W3C recommendation to have an 'alt' attribute
for images and 'title' for textual links - but I'd like to hear from others
on this.
