For a SimpleContext, or something similar: 
 
The comparison operator could just compare the arrays containing the
internal state of Navigator. 
 
The hashcode would be the XOR of all elements in the array, that
implements java hashcode and equals in a compatible way with the
assumed rules in java libraries. 
 
Jimmy, I think my "SimpleContext" or whatever you want to call it, if
properly implemented and perhaps with a few extra functions&nbsp; could
solve all the problems of random access. 
 
I think we just want something with the functionality of push() and
pop() but that can be extracted and kept outside, memorizing the
equivalent of a single stack position, and perhaps with a bit more
functionality.

    <pre wrap="">Given that VTD-XML indices are, well, ints, would this

That seems like a simple thing to build even outside
of VTD-XML itself?

Just curious,
