Template:MTA

m: ;This version is common to all sites except Meta-wiki
 * Note: Hidden content.


 * This is a register macro that might alternatively be stated as :where 'm:' is the definition on all other English language sister projects. It's purpose is to simplify local output code and avoid precisely that sort of #ifeq: code statement in working templates such as Commonscat1, Wikipediacat1,... etc.


 * Locally on Meta (The different version), this template has the effect of replacing the full url version Some page name with a local wikilink version which will then reveal bad links (redlinks) if a page does not exist.


 * This is used in a number of templates as a sub-template for that reason, especially those needing interwiki portability.

This different method of implementation has instead a hardcoded different fixed value on and off Wikipedia when accessed by the identical template and so allows portable template coding.
