Let's start from the bottom up.  We already have the servlet API spec,
so how about architectural design specs.  Filip Hanik, in his Tomcat
Interceptors project, has some useful documentation and I have earlier
provided feedback to him.

However, I recently implemented a realm for TC 3.x and had some
difficulties.  I had to understand TC source code to get a feel for the
request processing architecture.  Some areas of Interceptors and
Contexts are still unclear.  For example, what are notes?  These are
referred to in ContextManager quite a lot and the SimpleRealm
implementation but the purpose of them in a mystery.  Questions on the
list didn't get replies.

What issues need to be considered when extending things like
BaseInterceptor with regard to the contexts, JVMs, class loaders and 
synchronisation requirements.

I know it's a moving target all the time but architectural specs would
help in getting more people involved in writing better code for the
overall project.
