[xsl] XPath that returns nothing

Subject: [xsl] XPath that returns nothing

What is the best XPath expression that is guaranteed to return nothing?
(best in the sense of simplest, always works and costs as little as
possible to evaluate). I was hoping it'd be the empty string but that
seems forbidden.

Thanks,
