There are standard namespace aliases in ODF, like text: or style:. You
can use loext: as a namespace that is intentionally not in the official
spec but is an LO extension.

It might be preferable to keep of-pie as a different chart type (adding a row instead of two columns). I also made arbitrary decisions about sizes and separation of the two chart parts in the rendering. It appears there's a UI group that meets. Are these choices the kind of things that could be put on their agenda?

Heiko leads that, and you can just mail design at global.libreoffice.org if
you want design input, see:

> - In the selection matrix mentioned above I added crude placeholder graphics that I created just by taking a screenshot of representative of-pie charts. But they look nothing like the graphics for the other chart types. Is there some prescribed process (or person) for creating uniform-looking UI graphics?

One way that works is to put a placeholder image (so you can test your
code) and then ask for help on the design@ list. I did something like
that myself in the past.
