Please do not use this syntax here.
We have a dbsfed syntax for this:
<pkg origin="jessie-backports">qemu-user-static</pkg>

this needs a bit different logic in 

elbepack/init/preseed.cfg.mako, but it would change from this:
----------------------------------------------------------------------------------------------------------
% for n in pkgs:
% if n.tag == "pkg":
%   if prj.has("mirror/primary_host") or not prj.node("mirror/cdrom") or n.et.text.find('/') == -1:
${n.et.text} \
%   else:
${n.et.text[:n.et.text.find('/')]} \
%   endif
% endif
% endfor
----------------------------------------------------------------------------------------------------------

to something like this:

----------------------------------------------------------------------------------------------------------
% for n in pkgs:
% if n.tag == "pkg":
%   if prj.has("mirror/primary_host") and n.et.attrib.has_key ("origin"):
${n.et.text}/${n.et.attrib["origin"]} \
%   elif  n.et.attrib.has_key ("version"): 
${n.et.text}=${n.et.attrib["version"] \
%   else
${n.et.text} \
%   endif
% endif
% endfor
----------------------------------------------------------------------------------------------------------

depending a bot on whether we want/need version locking. 

But this is probably necessary for aptly multiversion mirrors.
