This package does not supply fontconfig data.  We can wait for fontconfig
maintainer to update its base data but there are ways to nicely fix this
situation.  See http://bugs.debian.org/652516 for ttf-wqy-zenhei.

Also, I see not much reason to make complicated update-alternative when
we can chose fonts via fontconfig by using its user configuration or by
installing fonts-foo-priority package.  If we remove this virtual
package, this package becomes RC bug free.
#645140 [S|  |  ] [fonts-takao-gothic] fonts-takao-gothic:
        fonts-japanese-gothic is not registered as virtual package
#645143 [S|  |  ] [fonts-takao-mincho] fonts-takao-mincho:
        fonts-japanese-mincho is not registered as virtual package

I think introducing another configuration mechanism other than
fontconfig makes system complicated with no gain.  So this bug report is
discussion not only for this one but for all related packaes.
