public class FzyAttribClause
extends FzyClauseComponent
implements Observer, java.io.Serializable, XMLOutput

Class AttribClause implements the concept of a rule clause. Rule clauses are used both within the premise and the consequent/alternate consequent of a rule

A rule clause will contain the following:

attribOI -- the attribute Of Interest, the attribute that we are attempting to determine the degree of membership.
goalSet -- the fuzzy set contained within the attribOI that we are attempting to determine if this set displays any degree of membership.
If the goal set doesn't then this particular attribute clause will be evaluated to zero degree of membership (aka 'false').

Example: Amount_Of_Requested_PO is low.
We are interested in this only to the extent that the current domain value of Amount_Of_Requested_PO is within the domain of Amount_Of_Requested_PO.low. If it is not, then this particular clause is evaluated to be FALSE.

goalAttribute -- this is present only if the goal set is NOT present. The goalAttribute indicates that we don't know which set of the goal attribute is to be evaluated for membership.

Example: Amount_Of_Requested_PO is very above PO_Approval_AMT

In this case the attribute of interest is Amount_Of_Requested_PO. (The value of which we are attempting to determine if it is over PO_Approval_AMT).

The goal attribute is PO_Approval_AMT and we will need to determine the value of it before we can determine if Amount_Of_Requested_PO is very above PO_Approval_AMT.
