Template talk:sa-decl-adj

This template is called on the following page, https://en.wiktionary.org/wiki/%E0%A4%B8%E0%A4%82%E0%A4%A7%E0%A4%BF and a template is seemingly accurately generated there. How is this possible when there is not only no documentation, there is no template here for sa-decl-adj? There is nothing here and yet it somehow "works" on the rest of wiktionary. =Now I see it is visible in the edit tab but not in the Template tab.
