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 Publishing DTD, the <app-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.
