What CSS selectors are supported by the inliner?

I was wondering if there is a definitive list of CSS selectors that the Campaign Monitor inliner will support.

For instance I've found that chained classes such as:

.class1.class2 {...}

and nth child doesn't seem to work either

td:nth-child(2) {...}

I know most of these CSS 3 selectors aren't well in email clients but I think it would be nice to be able to use them and have the styles inlined.

On the other hand selectors that aren't inlined could be useful for styles that you don't want inlined.

So does anyone know?
