@Andrew,

I hadn't seen that they were supported, I stand corrected. However that
particular feature was for example purposes. Any unsupported feature would do.

@Marc,

A quick read of that page shows a pretty good solution. Has any word towards
implementing its recommendations been done?

Thanks for the *very* quick response.
