I believe this bug is also affecting the build of the Macaulay2 package.  From
[1,2]:

The error message is different. I'd say that this is a different issue.

Fair enough.  I think it's related -- the latest release is more strict about
DTD files -- but involving a different DTD file, xhtml-math-svg.dtd from the
w3c-sgml-lib package.  Here's the output of xmllint, which gives a bit more
info:


   %xhtml-qname-extra.decl;
                           ^

$ xmllint --noout --loaddtd /usr/share/doc/Macaulay2/Macaulay2Doc/html/_ideal.html file:///usr/share/xml/w3c-sgml-lib/schema/dtd/WD-XHTMLplusMathMLplusSVG-20020809/xhtml-math-svg.dtd:338: parser error : xmlParseEntityDecl: entity xhtml-qname-extra.mod not terminated Entity: line 2: "http://www.w3.org/Math/DTD/mathml2/mathml2-qname-1.mod";

                                                                   ^
Perhaps this should be filed against w3c-sgml-lib?
