Category: C (Functional modification of feature)
Use one of the following categories:
F (Critical correction)
A (corresponds to a correction in an earlier release)
B (Addition of feature),
C (Functional modification of feature)
D (Editorial modification)
Reason for change: Current method for extending SWE Common by deriving new hard typed structures can break interoperability when using generic software since there can be ambiguous situations.
Summary of change: Addition of new DerivableXXX types in the schema forcing the tagging of Data Components and DataRecord fields with appropriate attributes. This change is backward compatible.
Consequences if
not approved:
Without this change the implementation of a generic SWE Common parser is much harder and will lead to less robust software.
