Appendix Matter


Wrapper element for one or more appendices (<app> elements), which hold additional or ancillary material attached to an book


As set up in the NCBI Book Tag Set, the <app-group> element can contain both appendices and interspersed bibliographic reference lists, because some older NCBI Book Tag Sets make use of this model.

This element is the same as the Appendix Matter <appm> element used in AAP- and ISO 12080-derivative DTDs.
