Re: [docbook-apps] Cannot parse MathML dtd...

Well, I am able to validate your file using xmllint from the libxml2
package.  I downloaded the mathml2 DTD archive from
http://www.w3c.org/Math/DTD/mathml2.tgz, unpacked it locally, changed your
declaration to point to my files, added a <title> and <para> to your
article, and the file validates when I use "xmllint --valid --noout
filename.xml".

Perhaps the parsers you are using are in SGML mode rather than XML mode? The
fact that it thought a colon was an illegal character rather than a
namespace separator indicates it isn't using XML parsing.
