I was wondering if anyone knows of a published reference for a subjunctive of this form:
It is not possible that Alice have raised her hand that day and the prisoner be still alive.
I have been told that this is an example of a subjunctive present perfect, and even managed to find an example on wikipedia at https://en.wikipedia.org/w/index.php?title=English_subjunctive&oldid=740284437#Compound_forms.2C_auxiliaries_and_modals:
Occasionally, a present perfect subjunctive is seen, as in `It is important that he have completed two years of Spanish before graduation'.
but I have been unable to find a published example using a that-clause and the present perfect. Any ideas?
