@andy-goryachev-oracle 
That section is about cascading rules, and doesn't even mention lookups.  In fact, the whole CSS reference does not mention lookups (aside from mentioning that JavaFX has a "property lookup" feature, and an indirect mention in the form of "looked-up-color").

There is no mention how property look ups work (and what types it supports), how they should be named (any name is allowed as long as it is not a supported color name), or how they cascade (before this fix, they gave styles a new priority, after this fix, the priority of the style is unchanged).

As this is quite some work, I think documenting this feature calls for a separate task to avoid delaying this fix.
