How can a Question be auto-answered?

An Attribute is any Question which is used by a Knowledge Object and whose value is assigned during inference (i.e. its value is not obtained via user input). The source of the Attribute value can be external such as a Database or internal such as a calculation.

An Attribute must have its value assigned in a Script that gets executed before that Attribute is encountered during decision inference.

This assignment can also be made inside the OnCapture Event of the Attribute itself, to ensure that its value is always set wherever it is included in a Knowledge Object. In fact this how Calculated Attributes are implemented by the Add Calculated Attribute Tool.
