  • :missing_container — no META-INF/container.xml
  • :missing_opf — OPF file referenced in container.xml not found
  • :malformed_opf — OPF could not be parsed
  • :io — internal I/O failure

Build errors:

  • :missing_required_field — title, identifier, or language is missing
  • :invalid_chapter — a chapter's data is not valid UTF-8 XHTML
