This sounds Ok for me. We can first make the CSS skin (zope.app.css)
fit the standards. Later we can see if we should use this skin as the ZMI
skin.

Let's use the 'WCAG level A[1]' as the standard in the 
CSS skin '++skin++CSS' in the package zope.app.css.

We can use the cookie based tree in this skin and see if this
tree fit's to the standards.

Any other parts we have to refactor where the Rotterdam skin doesn't fit?
