Elements used inside the back matter (element <back>) of an article, to describe ancillary material such as an appendix
This parameter entity (%doc-back-matter-mix;) has been significantly remodeled in version 3.0 of the Tag Set. For users who customize the Tag Set, the values and/or usage in version 3.0 are not backward-compatible with that in previous versions of the Tag Set. Specifically, in prior versions the %doc-back-matter-mix; parameter entity included the %sec-level; parameter entity, which has been replaced by the %sec.class; parameter entity. This change has no effect on compatibility unless the derivative Tag Sets have been customized.
