+% This file demonstrates how to configure biblatex to prefix
+% numerical citations with a letter or a string. This will work with
+% all numerical styles which ship with biblatex. Note that you must
+% set defernumbers=true globally when using prefixes.
+%
+% Since the prefixes are assigned as the bibliography is generated,
+% you may use any filter supported by biblatex to subdivide the
+% references (by type, by category, by keyword, etc.).

+This example demonstrates the quite complex options for assigning
+labelprefices to bibliographies and how citations decide which bibliography
+to point to. The default rule is that a citation will point to its entry in
+the last bibliography in which it appears. This can be overridden by
+explicit assignment to particular refcontexts with the
+\cmd{assignrefcontext*} macros.\\

+% Using a custom data model to declare the "coauthor" field
+\usepackage[style=authoryear,datamodel=95-customlists,backend=biber]{biblatex}
+\addbibresource{95-customlists.bib}
+
+% 1. First, check if the author list contain me, here, "Arthur Smith" (and
+%    isn't *just* me as then we can ignore this entry as there are no coauthors)
+% 2. Copy the author field to a temporary field "coauthortext". We don't need
+%    datamodel declarations for this as this will be deleted after use and
+%    will never get anywhere near code that queries the data model.
+% 3. Remove me (Arthur Smith) from this temporary copy of the author list
+% 4. Turn the resulting field into a comma-separated list
+% 5. Loop over this comma-separated list, creating new entries of type
+%    "coauthor" each with a "coauthor" name list field containing the data
+%    from the loop variable
+% 6. Remove the temporary author field copy "coauthortext"
+%
+% The special $MAPLOOP variable holds each value of the csv field named by
+% the "foreach" option on the \map macro.
+% The special $MAPUNIQ variable is a random string generated automatically
+% at the beginning of each \map section. This is useful when you need a unique
+% string as we do here because citation keys should be unique.
+% $MAPLOOPVAL can be used to refer to the last created $MAPUNIQ
