I remember Hyatt talking about this on irc sometime ago. A 2nd xul namespace for new widgets, such as my <expander> and whatnot which won't make it into the xul1.0 spec but which would be usefull in the product. sballard suggests "/keymaster/gatekeeper/actually.theres.also.xul2"

I prefer `lets.hope.we.never.reach.xul2'

Surely the new URL should be based on the baddie's name in Ghostbusters II :-)

... which seems, after a bit of searching imdb, to be "vigo"

Why bother with a new namespace when XUL1.0 isn't final or even implemented fully anyway?

doron says the <disclosure> stuff depends on this, marking dependency

I don't recall the exact words, but I think the quote where xul told them to choose the form of the one who would come to destroy them might work for this. Something along the lines of http://www.mozilla.org/keymaster/gatekeeper/choose.the.form.of.the.destroyer or however the quote went. Unfortunately, this lacks the elegance of ending in the xul extension. If that is strongly desirable, then maybe something more like http://www.mozilla.org/keymaster/gatekeeper/there.is.still.only.xul
