the alternate spelling of the name of the IMG element
I remember that jumped out at me when I read the HTML5 parsing spec, and I had no success whatsoever finding more information about it (try Googling "<image>"); do you have any links on how it came into existence? Or even better, a site that actually does this?
Fhars has the numbers involved, and you can search the mailing list on this. What I remember is, Ian Hixie was spec editor and was then working at Google. He would do bigtable queries over "all the HTML pages in the world" in some sense, and find out things like that so many million pages had IMAGE tags. So he would float to the list that it should be handled as a matter of robustness. And most of the time those queries would be inspired by someone's suggestion, although I think he had gone ahead and tabulated a frequency table. This way you could judge whether potential new element names would clash with mistakes authors were already making.
<dt>A start tag whose tag name is "image"</dt>
<dd>
<!-- As of 2005-12, studies showed that around 0.2% of pages used the <image> element. -->
<p><a href="#parse-error">Parse error</a>. Change the token's tag name to "img" and reprocess it. (Don't
ask.)</p>
</dd>
