This is a private module sandbox of Benwing2, for their own experimentation. Items in this module may be added and removed at Benwing2's discretion; do not rely on this module's stability.

Meant to be called from a module. `data` is a table containing the following fields:
* `lang`: language object for the hyphenations or syllabifications;
* `hyphs`: a list of hyphenations/syllabifications, each described by an object which can contain the following fields:
  ** `hyph`: list of syllables comprising the hyphenation or syllabification, each a string;
  ** `q`: {nil} or a list of left regular qualifier strings, formatted using {format_qualifier()} in
     [[Module:qualifier]];
  ** `qq`: {nil} or a list of right regular qualifier strings;
  ** `qualifiers`: {nil} or a list of left regular qualifier strings; for compatibility purposes only, do not use in new
     code;
  ** `a`: {nil} or a list of left accent qualifier strings, formatted using {format_qualifiers()} in
     [[Module:accent qualifier]];
  ** `aa`: {nil} or a list of right accent qualifier strings;
  ** `refs`: {nil} or a list of references or reference specs to add after the pronunciation and any posttext and
     qualifiers; the value of a list item is either a string containing the reference text (typically a call to a
	 citation template such as {{tl|cite-book}}, or a template wrapping such a call), or an object with fields `text`
	 (the reference text), `name` (the name of the reference, as in {{cd|<nowiki><ref name="foo">...</ref></nowiki>}}
	 or {{cd|<nowiki><ref name="foo" /></nowiki>}}) and/or `group` (the group of the reference, as in
	 {{cd|<nowiki><ref name="foo" group="bar">...</ref></nowiki>}} or
	 {{cd|<nowiki><ref name="foo" group="bar"/></nowiki>}}); this uses a parser function to format the reference
	 appropriately and insert a footnote number that hyperlinks to the actual reference, located in the
	 {{cd|<nowiki><references /></nowiki>}} section;
  ** `sc`: {nil} or script object for this particular hyphenation/syllabification;
* `sc`: {nil} or script object for the hyphenations/syllabifications;
* `q`: {nil} or a list of overall left regular qualifier strings, formatted using {format_qualifier()} in
  [[Module:qualifier]];
* `qq`: {nil} or a list of overall right regular qualifier strings;
* `a`: {nil} or a list of overall left accent qualifier strings, formatted using {format_qualifiers()} in
  [[Module:accent qualifier]];
* `aa`: {nil} or a list of overall right accent qualifier strings;
* `caption`, {nil} or a string specifying the caption to use, in place of {"Hyphenation"}; e.g. use {"Syllabification"}
  if what is passed in is actually a syllabification, as is common; a colon and space is automatically added after the
  caption;
* `nocaption`: if true, suppress the caption display.
