ARCHIVE attribute on APPLET ; warning, it contains a list of URIs.
Easier way of organizing the list:
a: href
area: href
base: href
body: background
blockquote: cite (not normally rewritable)
link: href
frame: src, longdesc
iframe: src, longdesc
input: src, usemap
form: action

script: src
applet: codebase, archive <list>
object: codebase, data, classid, usemap
head: profile
del: cite
ins: cite
q: cite
