Internal details[edit source]

{{NAMESPACE:{{{1}}}}} determines the namespace prefix without colon; it is empty both if the parameter has no prefix at all, and if it starts with a colon. To distinguish these two cases, {{NAMESPACE:Template{{{1}}}}} is considered: if that is empty the parameter does not start with a colon.
