Hi all,

I'm currently working on an expansion of the L-System Extension (just for fun, getting to know XML and Python). I implemented an extra parameter "Factor", such that the fractal scales with each level. More info about this at the Inkscape Forums: http://www.inkscapeforum.com/viewtopic.php?f=5&t=6411

The thing is, I would like to include some examples in the extension. I thought of a drop-down menu (an "enum" type), with entries like "Koch Snowflake" and "Pythagoras Tree".

<param name="Examples" type="enum" _gui-text="Examples:">
   <item value="Koch_Snowflake">Koch Snowflake</item>
   <item value="Pythagoras_Tree">Pythagoras Tree</item>

When the user clicks on such an entry, appropriate values should be assigned to the fields (e.g. Axiom="F", Rules="F=F+F+F", Factor="0.5", etc.).
I wondered whether this is possible using XML, or the Relax NG schema language?

So to be clear, the GUI-part isn't a problem. The UI looks like this at the moment: http://www.redpanda.nl/ExamplesInkscape.png
However, the "auto-assign" function needs to be implemented yet.
