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! Bob Stayton wrote: 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.

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
