I have update the picture on this page:
-<http://docs.codehaus.org/display/GEOTOOLS/Feature+Model+Proposal>

And included a picture of SimpleFeature as well.

This has any/all feedback from the last couple weeks and is test implementing.

Goals of the test implementation:
- verify that Gabriels use cases can be supported
- verify that XPath can be supported

For this test implementation we should consider the following:
- have test cases that demo support for the above goals
- clear readable code, if the code is difficult it is a bug
- use of GeometryAttribute to bind to JTS Geometry, we are focused on Features not geometry here

When it comes time do do the real implementation we will need to address a few more concerns:
- QName is defined by java.xml, we will need to locate or stub a 1.4 compatible 
jar
- Map of Hints for Factory configuration - I am not going through that again. Constructor/Setter injection, by hand or by container at the discretion of the application using geotools.

We may also wish to supply deprecated methods on SimpleFeature to ease the transition of client code.
