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.
