functx:has-element-only-content
=============================== 

Whether an element has element-only content

Description
~~~~~~~~~~~
The functx:has-element-only-content function returns true if the element has 
only child elements, with no direct textual (character data) content other than 
whitespace.

Technically, when a schema is not in use, the spaces and line breaks used to 
pretty-print XML documents do count as text nodes. However, for convenience, 
this function ignores them.
