livejournal changeset 15182: deleting all attributes for which tags?
I've been staring for a while at livejournal changeset r15182: LJSUP-4312, trying to figure out what it does and (more importantly) why. Apparently, it rewrites some tags so that <foo bar="quux"> becomes <foo>, but I'm not sure which. (It looks like most tags exempt from this rewriting are the lj* tags, but surely there has to be others, such as <a href=...">. Anyone has an idea?
