;;; Commentary:
;; This is an export library that uses CSL to process the citations and bibliography.
;;
;; It is intended for non-LaTeX exports, but you can also use it with LaTeX if
;; you want to avoid using bibtex/biblatex for some reason.
;;
;; The default style is set by a CSL-STYLE keyword or
;; `org-ref-csl-default-style'. If this is an absolute or relative path that
;; exists, it is used. Otherwise, it looks in `org-cite-csl-styles-dir' from
;; `org-cite' if it is defined, and in the citeproc/csl-styles directory in
;; `org-ref' otherwise.
;;
;; The default locale is set by a CSL-LOCALE keyword or
;; `org-ref-csl-default-locale'. This is looked for in
;; `org-cite-csl-locales-dir' if it is defined, and otherwise in the csl-locales
;; directory of `org-ref'.
;;
;; Note that citeproc does not do anything for cross-references, so if non-LaTeX
;; export is your goal, you may want to use org-ref-refproc.el to handle
;; cross-references.
;;
;;; Formatting Limitations:
;;
;; Different export backends have different formatting capabilities. HTML and
;; LaTeX support full CSL formatting including small caps, italics, bold, etc.
;;
;; The org-mode backend has limitations because org-mode syntax does not support
;; small caps. Many CSL citation styles use small caps for author names, so these
;; will not render correctly when exporting to formats that use the org backend
;; (like DOCX by default).
;;
;; For DOCX export with better formatting support, set
;; `org-ref-docx-use-html-backend' to t. This causes citations to be rendered
;; as HTML which pandoc can convert to DOCX while preserving formatting.
;;
;; See `org-ref-backend-csl-formats' to customize backend mappings for different
;; export formats.

"Mapping of export backend to csl-backends.
Each entry maps an org export backend symbol to a citeproc-el backend
format used for rendering citations and bibliographies.
Note: The 'org backend has formatting limitations because org-mode
syntax does not support small caps. CSL styles that use small caps
(common for author names) will not render correctly when using the
'org backend. For DOCX export, consider setting
`org-ref-docx-use-html-backend' to t to use HTML formatting which
pandoc can convert while preserving small caps and other formatting.
Available citeproc backends:
- html: Full HTML formatting with CSS styles
- latex: Full LaTeX formatting with commands like \\textsc{}
- org: Org-mode markup (limited, no small caps support)
- org-odt: ODT-specific XML formatting
- plain: Plain text with no formatting"

When non-nil, citations exported to DOCX will be rendered using the
HTML backend, which preserves formatting like small caps and italics
that pandoc can convert to DOCX.
When nil (default), uses the org backend which has limited formatting
support due to org-mode syntax limitations. Specifically, org-mode has
no native syntax for small caps, so CSL styles that use small caps
(common for author names in many citation styles) will not render
correctly in DOCX output.
Note: This option only affects DOCX export via pandoc. Other export
formats (HTML, LaTeX, ODT) are not affected.
See also `org-ref-backend-csl-formats' to customize backend mappings
for other export formats.
