Once again, I want to thank Robby Villegas for helping out with
comparing HTML4.0 entities and appendix C entries against the chapter
six tables.

The following list contains names that HTML4.0 and MathML have in common,
but whose unicode point listed differs for the name.
A large number on this list were pointed out in the earlier check
and are the result of having two unicode values associated with the
same greek name (eg, Alpha refers to both the capital and lower case
greek letter).  Not all are of this variety though.

Tau        {03A4}    {03C4}
tilde      {02DC}    {0303}
uml        {00A8}    {0308, E450}

Zeta       {0396}    {03B6}



The following is a list of names that are part of HTML 4.0 but are
not listed as part of MathML.  In most of the cases, these names
refer to letters.  Patrick previously explained why letters are not
listed.  However, 'epsilon' and a few other Greek names are missing.
The previous check turned up some other problems with Epsilon.

Finally, below is a list of character names from appendix C that are
not in the table.  A few of these were turned up in the previous check,
but most were not.  Obviously, either the tables need to be amended
or appendix C needs correction.
