Custom

Use the custom option to crossref to define new types of cross reference. For example:

---
crossref:
  custom:
    - key: vid
      kind: float
      reference-prefix: Video
---

kind	The kind of cross reference (currently only “float” is supported).
reference-prefix	The prefix used in rendered references when referencing this type.
caption-prefix	The prefix used in rendered captions when referencing this type. If omitted, the field reference-prefix is used.
space-before-numbering	If false, use no space between crossref prefixes and numbering.
key	The key used to prefix reference labels of this type, such as “fig”, “tbl”, “lst”, etc.
latex-env	In LaTeX output, the name of the custom environment to be used.
latex-list-of-file-extension	In LaTeX output, the extension of the auxiliary file used by LaTeX to collect names to be used in the custom “list of” command. If omitted, a string with prefix lo and suffix with the value of ref-type is used.
latex-list-of-description	The description of the crossreferenceable object to be used in the title of the “list of” command. If omitted, the field reference-prefix is used.
caption-location	The location of the caption relative to the crossreferenceable content.
