SoaML example model

[tlw1999]

I'm new to EA and even newer to SoaML, but want to understand how to create a SoaML services model.  I've tried to build up a model using the overview and EA help but with no success.  Does anyone have step by step guidance on which diagrams and objects need created and in what order or better yet does anyone have a SoaML model built in a project file that I can use to understand how the model is built up.  I can't seem to do something simple like: Create and use an object instance of <<participant>> stereotype with name X of class type Y in a collaboration diagram of SOaML stereotype <servicesArchitecture>>. At least not and get the result to retain the stereotype and look as it does in all the guidance/white papers.  The guidance implies that one can start with a services architeture diagram and then flesh out the detail.  There must be a sequence to creating the model that I suspect is not immediately obvious.  Any help will do.
