One might argue that in the arena of forward based streaming processes, 
nothing has been read. I would assume that the XPaths used during the 
streaming would be pre-compiled and evaluated-- in which case, and 
according to your statement it could be resolved. I had anticipated that 
this is what you meant by caching.
