Inside the spring module that I created, they're marked as required. This
has the benefit of when people declare abdera-spring in their maven build it
pulls in the dependencies automatically.

However, at the moment its probably not that big of deal. I'll change the
patch to put it in the server module with an optional dependency. In the
future though, I may bring this issue back up again though as there may be
both client & server related spring code. In which case I'd want to share
stuff like AbstractSingleBeanDefinitionParser between the two modules. Which
would imply the need for a separate spring module.

The xml handling part of it it really orthogonal to the spring
AbderaServlet. The XML handling part is for configuring a ServiceContext.
The HttpRequestHandlerServlet approach, as I understand, it can't really
replace this - it could only replace the AbderaServlet which is pretty
simple itself. Does that make sense or am I off in my understanding of what
you're describing?
