Skeleton Champion Question

[sciencerob]

A skeleton champion retains its intelligent and even keeps its class HD (Best 1). Looking at the example they provided it even has plenty of feats (looks like 3).

I understood that skeletons lost all their class features but this has me wondering if a Skeleton Champion keeps any class abilities (IE could a Cleric Skeleton Champion cast?)

Some skeletons retain their intelligence and cunning, making them formidable warriors. These undead are far more powerful than their mindless kin, and many gain class levels.

Emphasis mine. If it has class levels it has all the abilities associated with those class levels.
