Hello David,

   Thank you for your help.

Each MathML example is kept as a separate file, and I 
use PHP to include each file in the final webpage.  This
way all the code for an example is in one place and I can 
hyperlink to the MathML code for each example.  Each equation
is surrounded by a hyperlink to the source code that made it.
All the source code, Tex and MathMl, can now be had just by 
clicking on the representative equation.

Thank you, this fixed the problem of right and left angled brackets.
