Comment 1 for bug 540628

It's the same layout that was used by gnome-doc-utils, and Mallard documentation is still using it for building translations. That relies on xml2po to extract PO/POT files, so nothing is different except the XML schema. It'd be nice to support it, along with native support for other XML formats (like DocBook), but it's a lot of effort and it's not happening anytime soon.

Launchpad doesn't support that layout, unfortunately (so, it didn't work for gnome-doc-utils DocBook documentation either). They are also two separate problems: we can add import queue support for such PO directory layout independently from adding support for the actual XML format extraction.
