Does object pascal allow a class declaration marked as an abstract

The compiler will issue a warning if you instantiate a class with
abstract methods
Only if creating an instance straight from the class, eg:
This will warn:
begin
VMyObj := TMyAbstract.Create;
This wont:
var
VMyClass: TMyAbstractClass;
begin
VMyClass := TMyAbstract;
VMyObj := VMyClass.Create;
