That means that user agents, specifically browsers, can
have different interpretations of how to align a block
level math element.  So far, we have two interpretations
that I know of:

   * centered - Firefox
   * left-aligned - Amaya, WebKit

Users have filed a bug against WebKit, so there is at least
some expectation that it should be centered by default.

This is, of course, very easy to change but I'd rather it
be against some recommendation.  It would be better
to have a non-normative suggestion for a good default.
