Wrapper element for one or more appendices (<app> elements), which hold additional or ancillary material attached to an article
As set up in the Journal Archiving and Interchange DTD, the Appendix Group element can contain both appendices and interspersed bibliographic reference lists, because some older journal DTDs make use of this model.
This element is the same as the Appendix Matter <appm> element used in AAP- and ISO 12080-derivative DTDs.
