In XSLT 2 there is a function called empty.
http://www.w3.org/TR/xquery-operators/#func-empty
http://www.dpawson.co.uk/xsl/sect2/N3328.html#d3377e58
Defines two or three meanings for empty,
Contains no child nodes: not(node()) <empty/>
Contains no text content: not(string(.)) <empty></empty>
Contains no text other than whitespace: not(normalize-space(.)) <empty>
</empty>
Contains nothing except comments: not(node()[not(self::comment())])
<empty><!-- comment --></empty>
Which would you assume it meant?
