Extension to the base HTML transform type. Does numbering across the publication, back-of-the-box index, dynamic ToC
NOTE: Currently only works with the 1.8.5 Open Toolkit due to dependencies on the org.dita-community.adjust-copy-to plugin, which only works with 1.8.5. Work is under way to remove this limitation so the transform will work with OT 1.7.5, 1.8.5, and 2.1+.
== Updates
