Actually, this spec is being replaced by a CSS3 module: basic user interface
- which will hopefully be published any day now, and has dropped the
"user-*" properties due to lengthy reconsideration.

Not an error, perhaps just ill-conceived.

It is technically possible to have a property which affects a pseudo-class,
you just have to disallow (e.g. Ignore) setting that property in a selector
which contains that pseudo-class.  However even _that_ is limited in that if
you have two such situations, they could trigger each other.  And even then
it is possible, by disallowing setting both properties in both
pseudo-classes.

Needless to say this would add significant unnecessary complication to both
the authoring model and processing model, and therefore the group decided a
while ago to avoid these kinds of property/selector dependencies.
