Option to specify back matter for book

[adamiturabi]

Description

The back matter of a book may contain:

• appendices
• notes
• glossary
• bibliography
• index
• afterword
• acknowledgements

Some style guides may list the order in which these should appear. Usually they would be:

1. unnumbered
2. distinct from the appendices
3. optionally appear after the appendices

Would it be feasible for Quarto to add support for this (including for HTML format)?
