Can conditional attributes be assigned as conditions?

Arbitraty Example:

Attributes = Operating system, Version, Name
Options Opperating system = Linux {1}, Windows {2}
{1} Options Version = 2.2 {a}, 2.4 {b}, 2.6 {c}
{2} Options Version = ME {d}, 2k {e}, NT {f}, XP {g}
{1&a} Options Name = This computer
{1&b} Options Name = That Computer
{2&f} Options Name = Workstation

and so on..?
