Conceptually, I think VPCs are components first and foremost. So they are 
responsible for parsing their own configuration.

Fact that it is being parsed now by outer TreeProcessor is a shortcut I took. If 
VPC creates own inner treeprocessing environment and appropriate node builder 
(PipelineNodeBuilder, probably), it will be completely independent of outer 
TreeProcessor.

(I think I'm repeating myself)
