Hi Nathan,
Thank you for putting some thoughts into this problem.
Should I open a feature request ticket?

Yes I agree this would be very handy and something I was thinking
about how to tackle today. Larry has been working on some stuff for
the data-defined labels to make it easier to use from the UI and the
code so I'm thinking we can use the same code for that in the
symbols.
I would also like to be able to bind controls together, things like
fill and outline so they always stay in sync. I have a few ideas how
this could work so I'm going to try and have a go at some stage, or
at
least draft up the idea more.

Hi,
In many of my projects I need to do several classifications for
different graphical variables, like fill-color, stroke-color, size,
orientation, etc.
As an example I need to represesent manholes where the symbol shape
(SVG) is based on manhole type, the symbol stroke colors based on
the usage, and the size based on dimensions.
I know that it is currently possible to reach this goal by either
* using the rule based renderer - it would result in a lot of rules
or refined rules - a lot of work
* or concatenating the three attribute values into one attribute
and using the unique value renderer - but this results in many, many
combinations. Too many classes to handle.
So my question/suggestion:
Can we introduce multiple parallel/simultaneous categorized
classifications where each attributes controls one visual variable?
I don't know how one could display a legend then with such parallel
classifications ... but other than that it would be more convenient
for the user.
There may also be technical issues making this impossible.
Any thoughts on this?
Andreas
