You could use

test='not(.//*[local-name() != "vernac" and local-name() !=
"gloss"]/text()[1]
		| text())'

or

test='count(.//*[local-name() != "vernac" and local-name() !=
"gloss"]/text()[1]
		| text()) > 0'

These might be more efficient because you do not bother to examine
elements that will not cause a false result, and of the ones that are
examined, you only have to look at one text node.

Whatever expression you use, remember to use 

<xsl:strip-space elements='*'/>

Otherwise you will be counting whitespace-only nodes between elements,
which you most likely do not intend.
