NetAccessorException on http "Moved permanently"

Hi,

Xerces 2.7 throws a NetAccessorException when it tries to download the
MathML2-DTD and the webserver redirects with "301 Moved Permanently". I
think this is a bug -- Xerces should follow the redirect, instead it
simply gives up (I traced the connection with Wireshark/Ethereal).

Is there a better solution than rewriting the DOCTYPE entry?

for comparison:

wget http://www.w3.org/TR/MathML2/dtd/mathml2.dtd
--10:25:05--  http://www.w3.org/TR/MathML2/dtd/mathml2.dtd
           => `mathml2.dtd'
