Details
The condition is given as a boolean expression in the mandatory test
attribute. Because this expression must change its value if the loop is to terminate, the
condition will generally reference a variable that is updated somewhere in the loop using
a saxon:assign element. Alternatively, it
may test a condition that is changed by means of a call on an extension function that has
side-effects.
Note that the while loop does not change the focus: in particular, it does not change
the value of position().
