Common Required ID Attributes (a-group-CommonRequiredIDAttrs)
Local Attributes (defined for this element alone)
Attribute: sequence
Description
This attribute holds a number that represents the sequential location of the reference within the group of references at the end of an article. If this attribute is used on one reference it should also be used in all of the other references in the group, and there must then be no gaps in the sequence or duplicate numbers. If this attribute is not used at all, then the order of the reference elements within the XML document should serve as an implied ordering (and might be explicitly numbered using this attribute at a later processing stage).
Specification
This attribute is not required. It has text content.
