the last example of a filter expression says:
The following example illustrates the use of a filter expression as a
step in a path expression. It returns the element node within the
specified document whose ID value is "tiger":
fn:doc("zoo.xml")/fn:id('tiger')
That path expression has two steps, both of which are filter expressions
in the strict sense as zero predicates are allowed, but it isn't really
what one would naturally call an example of a filter expression in a
step.
fn:doc("zoo.xml")//*[@id='tiger'][1]
might be a better example (even if it's less efficient code)
