The <bind> Element

Definition and Usage

The <bind> element allows associating an interface of an object with a connector role.

If the referred connector role comes from a <simpleAction> element whose eventType is equal to “attribution”, and whose actionType is equal to “start”, and if the specified value is “$anyName”, the assigned value is retrieved from the property associated with the role “anyName” and defined by a <bind> child element in the same <link> element. If this value cannot be retrieved, no attribution is made.
