Reference locality expressions not working when citing a single bibliography item

[ronaldtse]

In ISO 19115-3 I wanted to cite "ISO 19115-1:2014 C.5 and C.6".

Metanorma supports various reference locality expressions relevant to this:
https://www.metanorma.org/author/topics/document-format/bibliography/#localities-2

• discontinuous locality (<<ref1,page=4,page=7>>)
• complex locality (<<ref1,part=IV,chapter=3;or!part=VI,chapter=9>>)

I tried this but it doesn't work.

<<ISO_19115-1_2014,clause="C.5;and!C.6">>

(renders as "ISO 19115-1:2014, C.5;and!C.6")

This also isn't ideal:

<<ISO_19115-1_2014,clause="C.5-C.6">>

(renders as "ISO 19115-1:2014, C.5-C.6")

I had to do this:
<<ISO_19115-1_2014,clause="C.5",clause="C.6">>

which renders as "ISO 19115-1:2014, C.5, C.6".

If we enable complex locality for bibliographic cross-references, then this should work:

<<ISO_19115-1_2014,clause="C.5;and!C.6">>

=> "ISO 19115-1:2014, C.5 and C.6"

I had to do this:
<<ISO_19115-1_2014,clause="C.5",clause="C.6">>

The intended formatting, as you would know if you had bothered to RTFM, or look at the examples,

Complex relations between discontinuous references can be specified by prefixing conjoining verbs to sequences of localities separated by semicolon

is:

<<ISO_19115-1_2014,clause="C.5";and!clause="C.6">>

sequences of localities means "clause=x", not just x.

Nonetheless, I've implemented the requested behaviour in postprocessing.
