The default DocBook-to-HTML conversion in XXE creates PNGs in the

How can I change this if I want to preserve the SVG images in the
generated HTML?
Which version of DocBook do you use? 4.x? 5.0? 5.1? I need to know
this to give you an accurate "recipe".
I'm using DB 5.0, but could probably also switch to 5.1, if it would
simplify the matter.
Thanks,

The simplest for you is to replace stock
<XXE_V9_install_dir>/addon/config/docbook5/docbook5_convert_input.incl
by attached, modified version of this file.
The differences between these two versions of
docbook5_convert_input.incl are shallow:
$ diff docbook5_convert_input.incl.STOCK docbook5_convert_input.incl

Note that the above changes will have an effect on, not only DocBook 5
conversion to multi-page HTML, but also to single page HTML and to Web Help.
We will make all DocBook (all versions) to HTML (all variants)
conversions in future versions of XXE preserve SVG rather than convert
this format to PNG. Nowadays all browsers support SVG really well.
