Subject: Simplest way to return an empty node-set

What is the simplest XPath expression that is guarenteed to generate an empty node-set in an doucment? I sometimes need to return an empty node-set from an function using the EXSLT functions module. Returning an empty string (the default return value for an EXSLT function) does not work for me.

I would think there would be a really simple expression for the empty node-set, but I can't find it. I've thought of using "self::*[2]", self::*[not(.)]" and "self::*[. != .]" but those seem rather hack-ish.

Any suggestions?

Thanks,
Brian
