(PREAMBLE: I'm not sure if the Product/Component for this bug is appropriate, change it if needed :P ) I've seen that xml translated docs in proj/* don't display the localized warning "original version of this document is more recent and it has been updated in ${date}", including the link to original english document. For example: the italian translation of gnome-2.18-upgrade.xml is outdated http://www.gentoo.org/proj/it/desktop/gnome/howtos/gnome-2.18-upgrade.xml but the warning+link is not displayed at all; instead, nvidia-guide.xml is outdated http://www.gentoo.org/doc/it/nvidia-guide.xml but the warning is displayed.
This is done on purpose because we can't rely on authors of /proj/* files to bump date/version properly, if at all.
