function definitions in XPath 3.x expressions

[Mukul Gandhi <gandhi.mukul@gmail.com>]

Hi all,

   I've come to know that, XPath 3.0 has introduced defining functions in XPath expressions, and calling these functions in the expression itself.

To understand this better, I'm looking for some examples of this. Can someone, please point me to some resources for this? Or may be, explaining with examples in this thread itself.
