There's a subtle error here. It should be

  a[a1[@attr = "key" and . = "Use"]]/a1[@attr = "val"]

You could read this as `the set of a1 elements with attribute attr equal
to "val", whose parent element is an a element which has a child a1
element, which has attribute attr equal to "key" and whose text content
is "Use"'.

The incorrect version might read `the set of a1 elements with attribute
attr equal to "val", whose parent element is an a element which has a
child a1 element which has attribute attr equal to "key" and which also
has a child a1 element whose text content is "Use"'.

Sorry.
