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.
