========================
functx:has-empty-content
======================== 

Whether an element has empty content

Description
~~~~~~~~~~~
The functx:has-empty-content function returns true if the element has no content 
at all (not even whitespace.) This is in contrast to the fn:empty function, 
which will return true for any element regardless of whether it has any content.

To test whether an element has any content besides whitespace, see the 
functx:all-whitespace function.
