It's a valid expression but not a valid pattern. The match attribute of
xsl:template expects a pattern.

If you really want to write a pattern that matches any text node that is the
first descendant text node of an item, you can write it as

text()[generate-id()=generate-id((ancestor::item//text())[1])]

But I wouldn't; I would find a different way of solving the problem.
