Optional_Optional_Each linkage will be registered as a fragment and have at least one name. A single name shall be assigned to each linkage
Optional_Residues shall be captured as described in 5.3.6.8.3
OptionalconnectivityThe entity that links the sugar residues together should also be captured for nearly all naturally occurring nucleic acid the linkage is a phosphate group. For many synthetic oligonucleotides phosphorothioate linkages are often seen. Linkage connectivity is assumed to be 3’-5’. If the linkage is either 3’-3’ or 5’-5’ this should be specified
OptionalextensionAdditional content defined by implementations
OptionalidUnique id for inter-element referencing
OptionalidentifierEach linkage will be registered as a fragment and have an ID
OptionalmodifierExtensions that cannot be ignored even if unrecognized
OptionalnameEach linkage will be registered as a fragment and have at least one name. A single name shall be assigned to each linkage
