There is no way you are supposed to do it. Both methods are equally valid. 
Both have their pros and cons.

Up till now I used the "node in the road" method. But lately I have been 
thinking about how routing applications would use osm data. I doubt bus 
companies will be using osm to route their busses. But when routing for 
pedestrians, you will want to be able to reach the bus stops.

Around here a lot of bus routes follow roads that are not accessible for 
pedestrians. The bus stop is then accessible e.g. from the back (from a 
parallel road/cycleway) or by a short section of sidewalk (from the nearest 
crossing). Since way-objects have no width you need to draw a piece of 
non-existing footway in the first case. The second case leads to splitting of 
the way into sections ("foot=no" for most of the road and no "foot=" tag for 
the section with the sidewalk.

I haven't found an simple and easy way to tag all this.
