Well, the wiki page mixes up different cycleways (for the situation in Belgium):
The first two are fietspad/piste cyclable according to the highway code.
-cycleway=track: compulsory separated from the road, usually with a D7 traffic sign..
-cycleway=lane: compulsory, part of the road, indicated by dashed line on both sides. Not to be mapped separately.
Is automatically exclusive.
-cycleway=shared-lane: non-compulsory " suggestions", which are not embedded in the highway code and can be anything suggesting the presence of bicycles: coloured lanes, chevrons, pictograms, dashed line on one side, anything.  cycleway:lane=advisory/exclusive simply does not apply anywhere. cycleway=shared_lane is always advisory, cycleway=lane never is.


And yes, in Belgium you can find cycleways indicated with both a D7 traffic sign and dashed lines. "Soft" separation means shared_lane.

To add to the confusion, the same page at one point says the opposite of 
cycleway:lane=advisory is ...=exclusive, and further down that its opposite is ...=pictogram.
