Bad template call: no text specified!

Usage (when used on a subpage of Wikijunior:Languages)
{{{{BOOKTEMPLATE}}/Note|text of note}}

The template will "complain" (as seen above) if the text is omitted. Note that no closing punctuation is provided by the template (i.e., if you want your note to end with a period, you must provide it).
