Attribute quantification constraints (AttributeQuantificationConstraint) are concerned with the value conditions of attributes underlying a behavior on a timeline. They are useful for declaring the variables (e.g. the input-, output- and internal variables of a function), their expected values and logical relations. An attribute quantification constraint can be expressed either by simple equations like F = m*a, V #gt;= 90, or dynamics models. When necessary, the straints on computational operations for data transformations and value assignment can be declared through the computation constraints (ComputationConstraint).<br/><br/>Semantics:<br/>The attribute quantification constraint specification is a pair/tuple of two sets: 1. the set of attributes for the behavior being specified; 2. the set of quantification statements over the attributes.<br/>
