Instead of web services, however, the SLA model deals with services in general, and instead of XML, it is language independent. The SLA model provides a specification of SLA(T) content at a fine-grained level of detail, which is both richly expressive and inherently extensible: supporting controlled customisation to arbitrary domain-specific requirements. The model has been applied to a range of industrial use-cases, including: ERP hosting, Enterprise IT, live-media streaming, and health-care provision. At the time of writing, the abstract syntax has
