true if the most recently closed subelement of the qualified element is specified, and
false otherwise. Replacing is with isnt will reverse the results.
last proper? subelement (of element-expression)? (is | isnt) (element-name | element-name-list)
last subelement is is an element test that evaluates to true if the name of the most recently
closed subelement is given in the test's list of element names.
When the keyword proper is specified, the last subelement is test ignores included
elements. If all of the subelements of the referenced element have been included elements, then the test will
fail.
When the last subelement is test is applied to the current element from an element rule, it fails
if the content has not yet been processed.
When invoked on ancestor elements, the last subelement is test is related to the previous
is test.
The following output action uses last subelement as a qualifier. This action will be executed only
when the last subelement of the parent element has a status of inclusion:
output "\par %n" when status of last subelement of parent is inclusion
