more or less. There were more of these originally. They relate to 
characters in MathML 1 and/or the STIX submission that didn't make it
into the proposals for Unicode 3.1 or 3.2.

As those proposals became more definite most of the "problem" cases that
I'd flagged with an x were resolved or removed.
Thanks for pointing out the remaining "x" versions. The "x" should just
be deleted making the names aliases (this is already done in the DTD)
So for example although the table has
DoubleLongLeftArrow,  U021D0x,
The DTD currently defines &DoubleLongLeftArrow; as &#x21D0; (without the
trailing x). Which means that DoubleLongLeftArrow is the same as 
DoubleLeftArrow. So now that the Unicode proposals have stabalised and
(unfortunately) the long arrows are definitely not in, the "x" can be
dropped. Will do that.

stylesheet error. These navigation links, like everything else, are XSL
generated. Will fix, thanks.
