Optional
_connectivityOptional
_nameEach linkage will be registered as a fragment and have at least one name. A single name shall be assigned to each linkage
Optional
_residueResidues shall be captured as described in 5.3.6.8.3
Optional
connectivityThe 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
Optional
extensionAdditional content defined by implementations
Optional
idUnique id for inter-element referencing
Optional
identifierEach linkage will be registered as a fragment and have an ID
Optional
modifierExtensions that cannot be ignored even if unrecognized
Optional
nameEach linkage will be registered as a fragment and have at least one name. A single name shall be assigned to each linkage
