title = "Definitions"

-- text.md --
A definition, indicated by an identifier starting with `#` or `_#`,
defines values that
are not output when converting a configuration to a concrete value.
They are used to define schema against which concrete values can
be validated.

Structs defined by definitions are implicitly closed.
