Up to now, this only concerned to messages like → Hi {{BASEPAGENAME}}!, what in
"User:Example/Archive/2010" looks → Hi Example/Archive! But now we have a {{gender:}} function to be used not only in user pages and discussions, but in MediaWiki interface messages.
As stated for instance in [[translatewiki:MediaWiki:Nstab-user/qqq]] documentation, "it is possible to use {{GENDER:{{BASEPAGENAME}}|male form|female form}} if needed". And it is what currently puts the Galician translation → [[translatewiki:MediaWiki:Nstab-user/gl]]. But BASEPAGENAME is only a partial approximation to the function needed, provided that it fails to return the user name in some pages.
You can see a live example of this issue at the user space of the female galician user [[:gl:Usuaria:Elvire]] and compare the user tab in her both subpages [[:gl:Usuaria:Elvire/Foo]] and [[:gl:Usuaria:Elvire/Foo/Bar]]. The former shows 'Páxina de usuaria' and the later states 'Páxina de usuario'.
Just as Niklas Laxström suggested to me in bug 30569, comment 11, I've created a simple {{SPACEUSER}} template at es:wikipedia, what is satisfactorily functioning in 15000+ user pages. But it is a local template based on #titleparts, not a MediaWiki function, so it can't be used in translatewiki general messages. I still think that a real {{SPACEUSER}} MediaWiki function should be created to fix this issue. Please excuse me for my poor English. P.S. Formerly, I've called this functionality as PAGEOWNER.
