xref.label-title.separator — Punctuation or space separating label from title in xref
This parameter allows you to control the punctuation of certain
types of generated cross reference text.
When cross reference text is generated for an
xref
or
olink
element
using an xrefstyle
attribute
that makes use of the select:
feature,
and the selected components include both label and title,
then the value of this parameter is inserted between
label and title in the output.
