The Stencil Group

Now, let's take a look at the Stencil Group's Web Services technology stack. It is similar to that of WebServices.Org with
three exceptions:
1. The WebServices.Org stack does not divide the layers into emerging and core components. Not doing so could confuse
the reader as to which standards are emerging. What is now an emerging standard would become a core standard at a
future date.
2. The Stencil Group does not apply Management, Quality of Service, Open Standards, and Security to any layer. The
reader could get the wrong impression that they are proprietary and treated as not important. When this happens, the
reader will opt for another architecture stack that has these features.
3. The Stencil Group starts the stack with undefined business rules while WebServices.Org begins with a clearly defined
business process such as service agreement. The reader could get confused on what undefined business rules are, and
how many would eventually be defined.
