[Dave Pawson]

The obvious question George - why doesn't the docbook
section need the attach?

Curious!

Re: [docbook-apps] NVDL, DocBook, and MathML

[George Bina]

Hi Bob,

Try adding an attach action on the MathML namespace. This will attach 
the content in MathML to the validation candidate triggered by the 
 action. Change the NVDL script as below:


http://purl.oclc.org/dsdl/nvdl/ns/structure/1.0; 
startMode="docbook">


http://docbook.org/ns/docbook;>


http://www.w3.org/1998/Math/MathML;>






Best Regards,
George

But when processed with NVDL, it fails with this message:

I think what is happening is that Jing has sent the  element to be
validated against the MathML schema, and then it sends the remains of
the inlineequation element to be validated against the DocBook schema.
But now inlineequation is empty, and fails validation.

I find if I insert an empty  inside inlineequation, then I
can work around this error.  Does anyone have any other ideas? That is,
short of customizing the docbook equation elements to allow them to be
empty.

Re: [docbook-apps] NVDL, DocBook, and MathML

[George Bina]

Hi Dave,

A DocBook document most probably contains only one 
http://docbook.org/ns/docbook section which has some other sections in 
the http://www.w3.org/1998/Math/MathML or other namespaces, like SVG 
maybe. The MathML does not contain DocBook further, if that was the case 
then we should have added maybe additional modes and decide what exactly 
we want to validate.


To account for other namespaces, like SVG, one may add also a namespace 
rule that will attach possible content in other namespaces to the 
current validation candidates:

  

Best Regards,
George

I find if I insert an empty  inside inlineequation, then I

short of customizing the docbook equation elements to allow them to be
