Is there an opportunity to use subtypes and domains in QGIS (Desktop 1.8.0) like the way it is used in ArcGIS?
I am specifically interested in the possibility of dependencies between subtypes and domains: not only a range or coded values for one field is required, but corresponding values.
For example: a subtype defines valid classes of land use categories like
01 - wood
02 - grassland
03 - urbanization
04 - ...
Associated to the subtype there are several domains describing the condition/worth of each category like
wood1 - deforestation
wood2 - conifer forest
grass1 - pasture
grass2 - hayfield
grass3 - grass
grass4 - ...
