Why not just use Operations?
Volume
Many domains (in Grid, systems management) have lots of
attributes
GetXXX/SetXXX becomes unwieldy
Explode WSDL
Explode size of client proxy
More difficult to detect the pattern across all operations and then
derive the attribute set
Just use Get(xxx) and Set(xxx)
But how does the Requestor reason about which xxx are valid?
Avoid situation of inheriting unwanted access
