| The |

| [Definition: The context position |
| is the position of the context item within the sequence of items |
| currently being processed.] It changes whenever the context item |
| changes. When the focus is defined, the value of the context position |
| is an integer greater than zero. The context position is returned by |
| the expression fn:position(). When an expression E1/E2 or E1[E2] is |
| evaluated, the context position in the inner focus for an evaluation of |
| E2 is the position of the context item in the sequence obtained by |
| evaluating E1. The position of the first item in a sequence is always 1 |
