Aloha Paul, et al, Not quite sure that (alt="") is not its intended or suggested use[1]. It appears that WAG suggests the practices that are being used[2]. For good measure, there is the MediaWiki page on formula display[3]. For tooltips, I thought that title="" was the appropriate use and not alt, but not sure how that works.
I can appreciate the desire to do something more than this, if only for the use case of "search for all documents that have the KR-20 formula"[4].
