The solution I was imagining would be like this:

Setup the following template matches:


Then, from the context of the parent to z:row, which is rs:data, my
apply-templates rule would somewhow seek the parent event source for
the z:row match when the immediate z:row was empty.

However, if the order in your source is not stable, you have to use some other system. Just use the xsl:choose to check if meet name is an empty string (remember to make sure you're checking if the value is empty, not if the attribute exists), then based on that select the result you want.
