CAM: A New Semantic and Structural XML Validation Technology
Brian M. Carey, IBM developerWorks
"XML documents are frequently validated against either a DTD or an
XML schema. Recently, a new technology called Content Assembly Mechanism
(CAM) has emerged. It is endorsed by the Organization for the
Advancement of Structured Information Standards (OASIS). CAM
represents a step up from XML schema because it provides even more
flexibility in defining both the semantics of an XML document and
the business rules associated with the actual data content...
One advantage of CAM over XSD is that localization needs are more
easily enforced with CAM. With XSD, enumerations are static and,
therefore, cannot be made context-aware. However, with CAM, you can
apply particular enumerations based on context values. In the emerging
global marketplace, the need for such streamlined validation should
be self-explanatory... CAM templates also provide next-generation
Service-Oriented Architecture (SOA) support. CAM supports business
processing technologies such as Business Process Execution Language
(BPEL), Business Process Specification Schema (BPSS), and Business
Process Modeling Notation (BPMN) modeling tools..."
