Parse a references spec as used in the {{para|ref}} param to {{tl|IPA}}, {{tl|IPAchar}}, {{tl|homophones}},
{{tl|rhymes}}, etc. and soon the {{para|f<var>N</var>ref}} param to {{tl|head}}. `parse_err` is a function of one
argument to throw an error with the specified argument as the error message; defaults to `error`.

Multiple references are separated by `!!!` (optionally with spaces around it), and the equivalent of
`<nowiki><ref name="bendo">{{R:it:DiPI|bendo}}</ref><ref>{{R:it:Olivetti}}</ref></nowiki>` can be specified using a
syntax like the following:

{ {{IPA|it|ˈben.do|ˈbɛn.do|ref2={{R:it:DiPI|bendo}}<<name:bendo>> !!! {{R:it:Olivetti}}}}}

To include a group as in `<nowiki><ref name="bendo" group="pron">...</ref></nowiki>` use:

{ {{IPA|it|ˈben.do|ˈbɛn.do|ref2={{R:it:DiPI|bendo}}<<name:bendo>><<group:pron>>}}}

To reference a prior name, as in `<nowiki><ref name="bendo"/></nowiki>`, leave the reference text blank:

{ {{IPA|it|ˈben.do|ˈbɛn.do|ref2=<<name:bendo>>}}}

Similarly, to reference a prior name in a particular group, as in `<nowiki><ref name="bendo" group="pron"/></nowiki>`, use:

{ {{IPA|it|ˈben.do|ˈbɛn.do|ref2=<<name:bendo>><<group:pron>>}}}

The return value consists of a list of objects of the form { {text = TEXT, name = NAME, group = GROUP}}.
This is the same format as is expected in the `part.refs` in [[Module:headword]] and `item.refs` in
[[Module:IPA]].

--[==[
Format a list of reference specs, using a parser function. The return string contains a footnote number that hyperlinks
to the actual reference, located in the `<nowiki><references /></nowiki>` section. The format an individual reference
spec 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 `<nowiki><ref name="foo">...</ref></nowiki>` or `<nowiki><ref name="foo" /></nowiki>`) and/or `group`
(the group of the reference, as in `<nowiki><ref name="foo" group="bar">...</ref></nowiki>` or
`<nowiki><ref name="foo" group="bar"/></nowiki>`).
