Format: The SchemeExtensions component shall contain a sequence of Scheme extensions whose format is left open. Each extension shall have an indication of its criticality. Semantics: Each extension of the sequence shall be selected by the LoTESO according to the information it wishes to convey within its LoTE. The meaning and value of each extension shall be defined by its source specifications being either the LoTESOs own definition or any other extension definition produced by another entity, such as a community or federation of schemes, a standards body, etc. The criticality indication shall have the same semantics as with extensions in X.509-certificates 12. A system using LoTEs shall reject the LoTE if it encounters a critical extension it does not recognize, while a non-critical extension may be ignored if it is not recognized.
