Perhaps there is a reasonable ground for advancement in XPath without
the train wreck of 2.0.
My basic problem with XPath is 2.1.3: "XPath is a strongly typed
language with a type system based on [XML Schema]."
Perhaps by discarding that mash, it would be possible to define a subset
of XPath 2.0 (and XSLT 2.0) which rescues "the good stuff" without
inflicting the "baggage" type system.
The committee could then continue to produce whatever complexity they
felt appropriate, while those of us who prefer our XML without the type
system could continue to get our work done and even advance a bit beyond
XPath 1.0.
As a developer planning an XPath implementation (for MOE and Regular
Fragmentations), this sounds to me like a potentially useful way to get
the most out of an untyped XPath.
