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:

http://www.sagehill.net/docbookxsl/GraphicSelection.html

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
