It would be really nice to have such streamable XPath subset strictly 
defined (and probably with different name). Many attempts to implement 
XPath in a streaming way, such as Microsoft's XPathReader [1] (which is 
actually used in Biztalk internally) are hardly widely usable primarily 
because of proprietary XPath subsetting.
