[tag] area_parameter

Typically boundary conditions are set on domains with dimension exactly one lower than the bulk mesh dimension. In some cases the boundary condition should be set on entities that have lower dimension than one lower. For instance boundary conditions on points in 2d or 3d domains or boundary conditions on lines in 3d domains.

In order not to integrate over a null set the area tag can be used to specify the area the boundary condition should be effective.
