			Two categories (with slash in the middle) can be assigned to a single vector feature in a single layer. This can happen e.g. when importing overlapping polygons:

			91/230
			73/99
			196

'''Q:''' How to edit GRASS Attributes?

'''A:''' Some commands allow specification of attributes, shown as: attr=string|cat|double|coords|dim

The meanings of these terms:

* string: text label attribute
* cat: vector ID number
* double: double precision attribute
* coords: vertex coordinates
* dim: number of dimensions (2D, 3D etc)
