areas can be represented as areas through multipolygon relations which are 
always areas or by help of an additional tag (area=yes/no), or through 
plausibility (tags and their combinations may imply an area or not). There 
isn’t a dedicated area object, maybe this is what you meant. Areas are 
represented with ways, and tags or relations are required to define the ways as 
areas.

typically routing engines operate on graphs, i.e. they do not route diagonally 
across areas, but this isn’t related to the question whether there is a 
dedicated datatype for areas or not.
