Get the type of link linking the first of two conflicting nodes
with inheritable attributes to the base node (or one of the
nodes to which the base node links).

Java is a bit strange for not letting me put "public
GenericScheherID getType()" in the ValidPredicate interface,
because each ValidPredicate returns a different type for
getType() -- ValidProp returns PropType, for example.
All extending classes must implement a greaterThan(AttributeValue)
function that determines whether this attribute holds a value
greater than an argued string constant.
