Re: [docbook-apps] conditional processing with mathml and equations as images

Hi Tim,

That method would work, but the stylesheets already provide a 
mechanism for selecting different imageobjects for different outputs, without 
needing to use profiling.  You can use the role attribute, and then select 
which role value you want to use at runtime.  See this reference for more 
information:

If you use custom role values, you will need to set the 
'preferred.mediaobject.role' parameter at runtime.

Subject: [docbook-apps] conditional processing with mathml and 
equations as images

hi, I need to process my DocBook 5 xml to html for two different 
types of html: one uses mathml and the other type uses images for math 
content.  

Is the following pseudo-markup the appropriate structure? Here I use the 
informalequation element, but for a real document I would also include 
inlineequation with the same content structure.

informalequation

--mediaobject

----alt (contains escaped latex equation markup)

----imageobject condition=plain

------imagedata fileref=

----imageobject condition=fancy

------imagedata

--------mml:content

So I could process the xml with for condition=fancy to get the mathml 
rendered in the html and condition=plain to get img tags in the html.

Is this the right way to do this?

thanks,

--Tim
