The typed value (of say, a node) to me is more > useful within the processor and not very much to the end user .. it can make a lot of difference, if for example you have some elements containing dates and you want to compare the dates (as dates) with some other dates, if you extract the string value then it won't work and you'll have to explictly cast the string back to a date, but if you extract the data() it will be a date. Of course in many situations you select the element node rather than the text node or string value or data() so that often this typing will be inferred, but data() is still useful sometimes. Just as text() is still useful sometimes.
