Abstract: Utilizing reference/identification (ID) linking in extensible markup language (XML) wrapper code generation in a data processing system. A code generator receives a type document and reference/ID constraints document and accesses the reference/ID constraints document to translate between XML structures and object structures.

Abstract: A change can be identified in service level for a Web service for an entity from a first service level to a second service level. Active policies associated with the first service can be retrieved. The active policies can be policies of a set of different management products of a service environment. For each management product, policies associated with the first service level can be deactivated. Policies associated with the second service level can be retrieved. For each management product, policies associated with the second service level can be activated. In one embodiment, the activation and deactivation of policies can occur automatically using a service level manager that programmatically handles service level specific adjustments across management products.
