The value would be the last one with the fn:data function. The first one binds
the element node to a second variable but you already have one for that, so I
donbt see what that would be good for.
Selecting the text node children is something XPath allows you to do but is
usually not considered the value of the element.

In the end of course someone might want the value as an xs:date or some
duration and unless you use schema-aware XSLT/XPath the data function will not
give you that, you might need to explicitly use a constructor function.
