Validity Rule - Where does Element's {abstract} appear?

I can't seem to find the Validity Rule which stops element information
items being validated with respect to an abstract Element Declaration.
The rule appears for abstract ComplexTypes at cvc-complex-type.1.1 but I
can't find it in cvc-elt.  Is this rule somehow implicit?  If so from
which set of rules?
Thanks in advance,
mick.
