Thanks to an additional template created by Alexander Lakhin, which 
extends the 'nochunk' stylesheet for SVG and MathML processing, it is 
now possible to create the "single HTML file" of our documentation 
including SVG. For me this is a working solution as long as we use 
Docbook 4. After the migration to Docbook 5, both languages as well as 
full namespace support will be natively included in Docbook.

Does anyone faced some more problems? Or can we start to include the 
three first SVG graphics into PG's documentation?

Kind regards

Jürgen Purtz
