That's true, provided there's some RFC2119 appropriate justification.

That mail seems pretty clear to me. Unless I misunderstand, the
combination of show/actuate that you've proposed in that message
isn't allowed by SVG. So the SVG semantics don't apply.

At this point you've got a new language. As I see it, that's either an
error which often means that all bets are off: the browser might
report the error, ignore the element, perform some corrective action,

If it's not an error, then the browser SHOULD obey the XLink
semantics. I think this probably argues in favor of treating it as an
error of some sort.

I can do nothing but abjectly apologize for my tardiness again. But I
do hope that I've shed some light on the relationship.
