I would like more information about this type of construction. Good examples escape me at the moment, but it would be something along the lines of:
These conditions need to be satisfied for this plan to be successful.
I only know of it because I've seen it in newspapers/heard it on TV. But I would like to know more. Specifically, what type of construction it is, other infinitives of the same kind or family, when it can/should/shouldn't be used, etc.
Basically, a page of a grammar textbook that mentions this construction is what I would like to see.
