This data module represents a local attribute to an entity.
It defines a common characteristic for the entities, that can have different values in different entities (i.e. the creation time).
An attribute can represent a matrix, defining the number of rows and columns as parameters.
The attribute is created the first time it is assigned to an entity, using an Assign block. Its value can be changed any times and at any point of the flowchart diagram.
All the Attribute modules included in a model must have a different number (parameter n). That number is used to identify the attribute in the attribute list of each entity.
