Hi,
Any general entities like ∑ that you use in
your document must be declared, either in the document or the schema.
Since RelaxNG does not have a way to declare entities, your document must
reference the declarations of such entities. See:
In addition to the DocBook entities, the MathML DTD
also has many entities. If you decide to use those, you will also have to
include the declaration of those entities.

Oh! I was under the (wrong) impression that including the
namespace declaration in the customdocbook.rng schema was sufficient. I now
have the namsespace declaration in the xml document & now it does not
complain about the prefix "mml"; however, now upon validation, I get the
following error:
"The entity "sum" was referenced, but not declared."
at
line: <mml:mo>∑</mml:mo>
Am I missing
something ?

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.

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:

How to include Mathematical equations in DocBook 5 ?
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
