[Paraview] adding VTK sources and filters

[Michael Dussere]

Hi,
I'm trying to add a new VTK source for ParaView. I found the XML files 
describing user sources and I see them appear in ParaView menus when 
modifying the XML.

The first problem is that I can't find any documentation on the XML and 
it's DTD. And the second one is that I don't know where to put my 
compiled VTK class and how to relate it with the XML description.

If somebody could give me an example or point me to a documentation it 
would be great.

Thanks

Michael.
