Rules applied
See references/RULES.md for the full catalogue.
| Category | Key rules |
|---|---|
| Root | Must be <bookmap> |
| Order | DTD order enforced: (title|booktitle)?, bookmeta?, frontmatter?, chapter*, part*, (appendices?|appendix*), backmatter?, reltable* |
| Chapters | At least one <chapter> or <part> required |
| Booktitle | <booktitle> must contain <mainbooktitle> |
| Appendix | <appendices> and bare <appendix> must not be mixed |
Common edge cases
- A bookmap with only
<part>elements (no bare<chapter>) is valid — parts are checked <backmatter>before<chapter>→ Error (order violation)<booktitle>without<mainbooktitle>→ Error
