Hi, I'm a researcher working in the field of model-based user interface design. I'm currently using EMF+Databinding+XSWT/SWT in a runtime for a dialog modeling language (see http://www.idi.ntnu.no/~hal/research/diamodl/). From the description of UFace, it seems that it should provide a very good platform for such a runtime, with the benefit of supporting a very relevant set of UI toolkits.

My dialog modelling language essentially models flow of data in a data binding graph, activation of UI elements based on a State charts and composes the final UI from XML fragments. With UFace, how do you actually implement compose the UI from widgets? Using a uniform (creation)API in UFace, or do you perhaps have an cross-toolkit XML language like XSWT?
