It appears the explanation is here:
The Mozambique projects point to this page which describes how to map using
a town as an example, they do not reference the African highway tag wiki
http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa. Only secondary,
tertiary and residential roads are mentioned and nothing is there for more
rual areas nor is there any mention of paths or tracks. It also explains
why I've seen buildings mapped with a name tag of thatched roof. I'm not
sure why the buildings are differentiated by metal or thatched roof, my
understanding is they all get mapped building=yes.
We have mappers who are very experienced in mapping in Africa tagging one
way, we have new mappers trying to apply the instructions in the link for
urban areas to rural areas and the result is inconsistent mapping.
Nothing in the Mozambique Guide is contra to the African highway tagging
wiki it just doesn't go far enough for rural areas.
If someone could wave a magic wand conciliate the two I would be grateful.
Note to Courtney I think you have some connections in the Peace Corps.....
