2. CMMN 1.1 CONTEXT
The RTF made changes that:
Corrected features in order to improve
implementability and adoption of the
standard
Corrected errors in the specification
Increased the clarity of the specification

Vendor Extensions

Edge type DepictionThese extensions can be added while maintaining
conformant CMMN file format
Receiving vendor can ignore extensions they don’t
understand but must re-export them unchanged
These extensions are maintained during roundtrip
Exporting vendor can add extensions they want and/or
need for their tool smart

Edge type Depiction
Fixed inconsistencies in UML model diagrams and
attribute tables in spec
Removed limitation on PlanItemDefinitions serialization,
added a constraint for scoping of PlanItem, and added
an example of scoping
Allowed Sentry to cross Stage boundaries for PlanItems
only (not for Discretionary Items)
Added "name" property to DiscretionaryItem
Clarified PlanItemControl of Discretionary items
(repetitionRules)

Fixed inconsistencies between UML and XSD
Clarified CaseFileItem containment and references
Fixed expression description to allow constant
expressions
Introduced Documentation class

Come do a trial of the future
BPMN + CMMN + DMN
The triple crown of process improvement standards
