You need to define the mml prefix in the source document:
<book xmlns:mml="http://www.w3.org/1998/Math/MathML">
| Trying system delegate file:///etc/xml/docbook-xml.xml
| Resolve URI
| http://www.oasis-open.org/docbook/xml/mathml/1.0/dbmathml.dtd
| I/O error : Attempt to load network entity

| validity error : Could not load the external subset

Are you sure that there is an entry for the public or system ID for
dbmathml.dtd in the catalog file?
Something like this is needed:
<public publicId="-//OASIS//DTD DocBook MathML Module V1.0//EN"
uri="file:///your/local/path/to/dbmathml.dtd"/>
Furthermore, dbmathml.dtd contains a reference to
http://www.w3.org/TR/MathML2/dtd/mathml2.dtd, hosted by W3C. They do not
like repeated requests for the same resource. See
http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic.
So you should have a catalog entry for mathml2.dtd too.
