Template:Citation Style documentation/deprecated

In addition to the deprecated parameters, the few remaining unhyphenated aliases of multi-word parameters are discouraged for use in citation templates. They have been removed from the templates' documentation and are kept only for legacy support. To streamline the appearance and improve consistency across the project, these variants should no longer be used when adding parameters to citation templates. Instead, select the hyphenated parameter variants and also consider switching other non-hyphenated parameters, which may be present in a citation already, to their hyphenated equivalents at the same time. (Bots are allowed to replace them only while carrying out other (non-cosmetic) edits as well.)
