1.1.1 This Document is Created from the ETP UML Model

ETP has been designed and developed using UML® implemented with Enterprise Architect (EA), a UML modeling tool from Sparx Systems. The document contains these basic types of content:

• Normative: Content generated directly from the UML model. Normative content is the required information that defines mandatory behaviors and rules of ETP.

• Non-normative: Supplemental explanatory content (like this introduction chapter). Non-normative content provides necessary context for understanding ETP and how it works. It does not define specification behaviors.
