Test elem1 in the test suite

Test elem1 is:

a: "a", b, c.
b: "b", c, d.
c: "c", []. {it should block here, since nothing matches}
d: "d".

And it’s a syntax test that is suppose to fail:

    <test-case name="elem1">
      <test-string-ref href="elem1.ixml"/>
      <result><assert-not-a-sentence/></result>
    </test-case>

I interpret the comment to mean that this test should fail because “[]”
isn’t valid, but that’s not right:

-set: -"[", s,  member*(-[";|"], s), -"]", s.

What am I failing to understand about this test?

                                        Be seeing you,
                                          norm
