In order to exchange use cases based on the template which is defined in IEC 62559-2, this
part of IEC 62559 establishes the interfaces between the different use case repositories
and/or UML engineering software tools.
Therefore, this document defines the required core concepts and their serialization into XML
syntactic format of a use case template, an Actor list and list for detailed requirements.
The main purpose of this document is to propose an independent format for transferring the
use case information between modelling software. In order to satisfy this goal, the syntactic
XML format is chosen to serialize the use case data. This document defines in detail the core
concepts of the template into UML and their transformations into XML using the XSD
standard.
