Hi,
Well, any namespace you use in a document must be
declared in the document. If you are using DocBook5, you know how to
declare the docbook namespace in the root element's start tag. Do the same
for the mml namespace in the same place and it will apply to the entire
document. That should eliminate that error.

include Mathematical equations in DocBook 5 ?
Thank you for your reply.
Following the instructions
on http://docbook.org/docs/howto/#faq-customization-mathml,
I downloaded the MathML RELAX NG schema from http://yupotan.sppd.ne.jp/relax-ng/mml2.html
& unpacked it in "mathml" directory. Added the following lines to my
customdocbook.rng
<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0">
<include href="/path/to/docbook.rng">
<define name="db._any.mml">
<externalRef href="mathml/mathml2.rng"/>
</define>
<define name="db._any">
<element>
<anyName>
<except>
<nsName ns="http://docbook.org/ns/docbook"/>
<nsName ns="http://www.w3.org/1999/xhtml"/>
<nsName ns="http://www.w3.org/1998/Math/MathML"/>
</except>
</anyName>
<zeroOrMore>
<choice>
<attribute>
<anyName/>
</attribute>
<text/>
<ref name="db._any"/>
</choice>
</zeroOrMore>
</element>
</define>
</include>
</grammar>
Then, I added the following equation: <sect1><title>Equations
<title> <equation>
<title>My MathML
example</title>
<mml:math>
<mml:mrow>
<mml:mo>∑</mml:mo>
<mml:mn>4</mml:mn>
<mml:mo>+</mml:mo>
<mml:mi>x</mml:mi>
</mml:mrow>
</mml:math> </equation> </sect1>
in the
article. When I tried to validate it, (I'm using oXygen XML Editor) I
got error messages:
conflicting ID-types for attribute "linkend" of
element "msginfo" from namespace "http://docbook.org/ns/docbook" The
prefix "mml" for element "mml:math" is not
bound.
I read the information on: http://www.sagehill.net/docbookxsl/ProcesingDb5.html#Db5Validation However,
did not find it helpful, may be because I'm using the XML
editor.
Any idea, why does it not like/recognize the prefix
"mml"?
Thanks!

Hi,
In DocBook 5's RelaxNG schema, the imagedata, equation, and
informalequation elements can contain elements in the MathML
namespace. So the equation example in the book is still accurate, you
can just skip the DOCTYPE declarations.
Once you mix namespaces,
though, validation becomes more complicated. See this doc for more
information:

Hi All,
I would like to know how to
include Mathematical equations in DocBook 5 ? I know of an example
listed on: http://www.sagehill.net/docbookxsl/MathML.html
However, it's using DB 4.5. I am using DB 5.0.
Any examples
will be helpful.
TIA, Anagha
