SYSML2 — Issues with SysML grammar

Reuse of KerML rules in SysML grammar is not described sufficiently.
Not clear which rules are reused and which not.
Reused rules are simply missing from the SysML definitions.

Additionally,
1. AnnotatingElement defined twice: In 8.2.2.4.1 and in 8.2.2.5.2
2. Extra ')' in 8.2.2.15 AllocationUsageDeclaration
3. MetadataUsageDeclaration not defined, used in 8.2.2.26 in MetadataUsage
4. PerformActionDeclaration not defined, used in 8.2.2.17.3 in TransitionPerformActionUsage - should this be PerformActionUsageDeclaration?
5. StakeholderDefinition not defined, used in 8.2.2.5.2 in DefinitionElement
6. BindingConnector not defined, used in 8.2.2.6.4 in VariantUsageElement and 8.2.2.14.1 in InterfaceNonOccurrenceUsageElement - should this be BindingConnectorAsUsage
7. Succession not defined, used in 8.2.2.6.4 in VariantUsageElement and 8.2.2.14.1 in InterfaceNonOccurrenceUsageElement - should this be SuccessionAsUsage
8. AnnotatingMember defined twice, in 8.2.2.8 and in 8.2.2.4.1
9. MessageEvent not defined, used in 8.2.2.13.4 in MessageEventMember - should the definition of MessageEnd (after it) be named MessageEvent?
10. ItemFeature not defined, used in 8.2.2.13.4 in FlowPayloadFeatureMember - should it be FlowPayloadFeature
11. ItemFlowEnd not defined, used in 8.2.2.13.4 in FlowEndMember - should it be FlowEnd
12. InterfaceNonOccurrenceUsageMember not defined, used in 8.2.2.14.1 in InterfaceBodyItem - should it be InterfaceNonOccurrenceMember
13. FeatureChain not defined, used in 8.2.2.16.5 in OwnedFeatureChainMember - should this be OwnedFeatureChain
