Why should we think that only a verb and not a noun could carry the mandatoriness or command factor? It is the necessity to comply with the said factor that decides use of the command word.
Look at this following sentence ‘Spoke’ by itself is not command word; It is the condition, a noun that implies the command and thereby justifies the subjunctive.
Several financial officers of the company spoke on condition
that they not be named in the press reports.
A. that they not be named
B. that their names will not be used
C. that their names are not used
D. of not having their names
E. of not naming them
The answer is A
Here is another example from Urch.com’s Erin
While many politicians have been able to abuse recent changes in the law, the original spirit of the bill was
that it was equally applied to all residents, no matter their socio-economic status.O that it was equally applied to all residents, no matter their socio-economic status
O that it was equally applied to all residents, and their socio-economic status did not matter
O that it was to be applied equally to all residents, no matter their socio-economic status
O that it be applied equally to every resident, no matter their socio-economic status
O that it be equally applied to all residents, no matter their socio-economic status
Here the command factor is derived from the word ‘spirit’ of the bill, which citizens are supposed to obey.
The answer is E.

Quote:
“When a verb, noun, or adjective of recommendation, requirement, or request is followed by a "that" clause, the verb in the "that" clause will be in the subjunctive mood. But a verb, noun, or adjective of recommendation, requirement, or request does not have to be followed by a "that" clause.”
