Eek! You are right.
Don't you need index-of-node?
That is an XPath 3.0 function. I need to stick with XPath 2.0. Suggestions?

Hi Folks,
The variable $A contains an element.
The variable $B contains an element.
I need an XPath expression that determines if $B is not contained in $A.
This XPath expression seems to work:
not(index-of($B/ancestor::*,$A))
but that seems awful, i.e., not straightforward, convoluted, and probably
inefficient.
If you have (element) nodes I fail to see how the index-of function helps that
works on sequences and uses "eq" comparison helps to check containment? Don't
you need https://www.w3.org/TR/xpath-functions/#index-of-node?
