Thanks Tim for responding to Brian.

I note that <log/> is an empty element and used as specified in the
MathML spec, i.e. the example is correct and not in error. I regret
that current browsers don't as yet support MathML, but we very much
hope this will be fixed in the next generation. Until then, you will
have to use other means for rendering math in Web pages. Further
details are available on the W3C math page:  http://www.w3.org/Math
