The element is actually in the METAL namespace; that is, its name
really is '<metal:block>', not '<metal>'. It exists for the relatively
rare case when macro expansion needs to be able to insert a slot into
the middle of another element, and can't be attached to any other
(legal) element (for instance, '<div>' is illegal inside the '<head>'

I don't think I've ever used '<tal:xxx>' for anything, although it
should be legal XML / XHTML. Normally, I have "real" elements to hang
the TAL off of.
