Hi guys, i am working on a software engineering design project at the part of architectural design of a Web Application. I am describing the operations of each Web Page according to IEEE specifications. When describing an operation i have to give 'attributes' and 'return' 'pre and post conditions' as well as 'exceptions'. How exactly we define and identify the 'attributes' and 'returns'?. For instance Does a button SUBMIT returns anything or have any attributes inside a web form?
Thx for your time.
