Looking at how the SLA is defined, each SLA has a service identifier and contract identifier. 

The combination of the service identifier and contract identifier uniquely identifies the 

service to the proxy. The service identifier and contract identifier are defined at the start of 

each SLA as follows.

Various other parameters were defined in the SLA but are not be mentioned here due to the 

fact that there are too many to list. However the actual SLA created is available in Appendix 

C for reference. The SLA created is based on the DTD defined in Appendix A.
