Someone just used an <onlyinclude> tag in a template in MediaWiki. From playing with it, it seems that the following two examples are identical:
===EX A <noincludeHeader</noinclude Template <noinclude>Footer</noinclude>
===EX B Header <onlyinclude>Template</onlyinclude> Footer
I could not find any documentation on MW.org, meta, en.wp or even Google, and it is not in any of the release notes going back to 1.6. Is this a hyper-new (1.9) feature, or just very poorly documented? If the former, is it safe to use it yet? If the latter, is there a reason for hiding this feature?
