[Harry Potter] Why does a school textbook give information on how to create Basilisks

*Fantastic Beasts and Where to Find Them* states, in no uncertain terms, that the breeding of Basilisks is illegal, and for good reason. Since they are uncontrollable except by Parselmouths, they are as dangerous to most Dark wizards as to anyone else. However, the book also provides very detailed information not only on how to breed a Basilisk, but on how to conceal it should it arise suspicion. It is stated that a Basilisk is hatched from a chicken's egg incubated by a toad.

If the creation of Basilisks is illegal, why would the instructions for doing so be included in a school textbook read by hundreds, if not thousands, of Wizarding children, some of whom might be tempted to try out what they read?

Technically the method described in that book is a matter of commonly understood folklore, and depending on where you're looking, it can't really happen except naturally. Anyway, there's no point covering up information that's common knowledge; you can't exactly hide what the chemical compound of methamphetamine is.
