Fix placeholder ... in descriptions for #668

The `...` syntax is popular for XSpec output in testing to say 'I want
to test the structure but don't care about the specific text value' or
attribute value. Our modern tooling doesn't understand that anyway, so I
am not clear given its generated schema checks with the new tooling.

This commit tests for that.
