[xsl] Determine if an element with descents has complete empty text cont

I've inherited some code that has this type of check to determine if an
element with arbitrary possible subelements has completely empty text
content:

normalize-space(string-join($context//text(), '')) != ''

In XSLT 2 I'm pretty sure there's a simpler and/or more efficient way to
do this. 


Is there a better way to do this and if so, what is it?

Thanks,

Eliot
