Separating business process from user interaction utilizing process-aware XSLT stylesheets

In the web context, it is difficult to disentangle presentation from process logic, and sometimes even data is not separate from the presentation. Consequently, it becomes crucial to define an abstract model for business processes, and their mapping into an active user interface presentation, using the principle of separation of concern between the process logic, data and its presentation aspects. We endeavour to extend declarative (rule based) XSLT to accommodate the separation of process information from the data structure and presentation, and thus propose to design process aware stylesheets, in a minimally invasive manner. The isolation of the three otherwise entangled aspects of web-processes makes it easy to develop and maintain web-applications in a more independent manner where each individual developer can focus on his/her primary responsibility, like describing the process, maintaining a database, or creating user interface (web-pages) without being levied any substantial effort to learn new technology.
