typical schemas look like < span class = "extract" > < span class = "extract-syntax" > X(*1, true) == *2< / span > < / span > , say, where some values go
in place of < span class = "extract" > < span class = "extract-syntax" > *1< / span > < / span > and < span class = "extract" > < span class = "extract-syntax" > *2< / span > < / span > . Those are the parameters, and they can be supplied
