well...

following-sibling::node()[1]/self::*

tests that the node immediately following the Pi is an element.

and

following-sibling::node()[1]

is the same as

following-sibling::node()

in a boolean context and tests that the PI has any following sibling.

So I think my code is closer to what you said your requirements are,
but whatever works:-)
