Right, using my optimizations.

In the case of my XPath implementation, I would support these via the
public DOM interfaces (yes, it would be slower).  Other implementations may
throw an error.

No, not if you don't support generic DOMs.

I don't think having a method on the Node object vs. having a method on an
XPath object that takes a node as a context makes one smidgen of difference
in terms of optimization or portability.  On the contrary, the method with
context is more portable.

According to your argument, anything that is ever optimized must be a
method on the DOM.
