  <!-- Contents:
    
       This file interprets Chicago using APA's four basic reference elements
       (cf. CMOS18 14.2, 14.64, 14.161):

        1. Author (CMOS18 13.74-86)
        2. Date (author-date system only, CMOS18 13.102)
        3. Title and descriptions (CMOS18 13.87-101)
            3.1. Title
            3.2. Description
            3.3. Identifiers (edition, contributors, volume)
        4. Source
            4.1. Serial sources
            4.2. Monographic sources
            4.3. Series
            4.4. Event
            4.5. Publisher
            4.6. Date
            4.7. Locator (including page references)
            4.8. Medium
            4.9. Archival location
            4.10. URL or persistent identifier
      
       Freeform annotations to bibliography entries: 
        
        5. Notes
       
       Chicago also provides parallel rules for legal references following
       The Bluebook: A Uniform System of Citation (code shared with APA):

        6. Legal references

  <!-- In this file, macros suffixed `-bib` and `-note` are parallel versions
       of the same features for the bibliography and notes, and all changes
       must be applied to both. They should only contain differences of
       punctuation (periods in bibliography, commas in notes) and capitalization,
       except where the comments indicate structural changes. -->
