Hello,
The entity &Integral; is defined in the MathML 2.0 dtd, but you have
to reference the dtd in a doctype declaration like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"  "http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd">

Subject: itex2MML doesn't support MATHML2.0

Hello,
  I use itex2MML to generate MATHML code.
  for example:

$ echo '$\int_a^b$' | itex2MML
<math xmlns='http://www.w3.org/1998/Math/MathML'>
<msubsup><mo>&Integral;</mo> <mi>a</mi> <mi>b</mi></msubsup>

</math>

  but I find that mathml2.0 doesn't support `&Integral;', 
for example

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="http://www.w3.org/Math/XSL/mathml.xsl"?>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>Optical Radiation</title>
  <body>
<math xmlns='http://www.w3.org/1998/Math/MathML'>
<msubsup><mo>&Integral;</mo> <mi>a</mi> <mi>b</mi></msubsup>

</math>
  </body>
</html>

when I use Mozilla Firefox 0.8 to view this page, I got an error.
XML Parsing Error: undefined entity
Location: file:///home/nichloas/public_html/WebWiki/mathml.xml
Line Number 8, Column 14:

<msubsup><mo>&Integral;</mo> <mi>a</mi> <mi>b</mi></msubsup>
-------------^

What's the problem??
