For HTML elements in HTML documents, why is Element.localName
uppercased for tag names and lowercased for attribute names? I
wouldn't expect it to, and it makes it harder to write scripts that
work for both HTML and XHTML. For example, if you want a script to
work in both legacy HTML UAs and HTML5 UAs as well as in XHTML, you
may want to do something like if ((elm.tagName == "A" && !
elm.namespaceURI) || (elm.localName == "a" && elm.namespaceURI ==
"http://www.w3.org/1999/xhtml";)) to check that a given element is
an HTML "a" element.
Good timing, mentioning this.
WebKit uses lowercase for localName for HTML elements in HTML
documents for the reasons you mention.
We received a bug report about a library, "Jira", that doesn't work
with Safari 3 because of this <http://bugs.webkit.org/show_bug.cgi?
id=14114>. We were surprised to learn that Mozilla uses uppercase.
