Your resend was also one of those nasty send-it-twice-as-HTML thingies, but
no matter, we'll survive:-)

No, relations are supposed to be rendered as equations, just as <apply>
renders a function application literally rather than trying to apply the
function. (In fact it is arguable that there is no difference at all in
meaning between <apply> and <reln>)

WebEq uses (or did use?) this tag. It is essentially just the early
name for <reln> so it should not be used with any software that has been
updated to use the final W3C recommendation version of MathML1.0 rather
than one of the draft submissions.

I'd do that, but using <reln> rather than <apply>.
