Template:Citation Style documentation/syntax
From WikiAnesthesia
Nested parameters rely on their parent parameters:
- parent
- OR: parent2—may be used instead of parent
- child—may be used with parent (and is ignored if parent is not used)
- OR: child2—may be used instead of child (and is ignored if parent2 is not used)
- Where aliases are listed, only one of the parameters may be defined; if multiple aliased parameters are defined, then only one will show.
If non-hyphenated aliases of parameters with hyphens are defined, they exist only for legacy support (and are subject to become unsupported in the future); therefore, to streamline the appearance and improve consistency, select the hyphenated variant when adding parameters to a citation template and also consider switching already present non-hyphenated parameters to their hyphenated equivalents at the same time.
