Sorry, it is not clear what the question really is...


One of the biggest advantages of having typed variables (including any
document, any parameters and results from an xsl:template or from an
xsl:function) is the static typed checking that will raise errors
during compile time, vs run time or never raised at all.

Without the typing feature of XPath 2.0/XSLT 2.0 one would need
type-inference/theorem-prooving just to deduce the types of any
programming-language item, and in order to fully understand a program
(even one written by themselves).

Another big benefit is a new, huge opportunity for optimization.

The obvious benefit of this feature is reduced developer time,
increased quality, safety and performance.

The combination of all of the above results in a quantitative leap
forward in development technology and programmer's experience. The
gross benefit goes also to the end user.
