According to IGN/NGI and the reasoning below, Benedestraat N211a is

The first question is; what is a "primary/secondary/tertiary road?".
And why is it useful to know? To make better GPS routing?
The current conventions are written more or less down here
http://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Conventions/Highways
(but the bit written after tertiary about suffix letters isn't really correct,
and the bit on trunk roads could be changed a bit to include express roads
that aren't motorroads but don't allow pedestrians and cyclists)
So we're using the road numbers to decide on secondary/primary. These rules
are up for debate but the problem is getting better definitions so we don't
risk getting into a discussion for every possible road where one person would
classify a road primary, while another one thinks it's secondary etc. (*)
The current rules aren't perfect but they generally give maps that are
satisfactory, since all important roads are managed by our regional government
and thus have road numbers, and thus are at least secondary.
I think in this specific case that OsmAnd_pieter is actually correct to
change this road into secondary. But I don't think it's _that_
important (between 2nd or 3rd). Let's be a sinner and think of 'the
map' displayed as it is. Trunk roads, Highways and primaries are
displayed with enough contrast. (green, blue , red).
The difference between 2nd and 3rd is hardly visible, I would say he's
right. I live in the area so I know what road that is and it's an
important one over here, so making it secondary isn't that far of reality.
