+    <summary>The author-date variant of the Chicago style adapted for German. I addition to the online reference I've used:
+      Turabian, K. L. (2007). A Manual for Writers of Research Papers, Theses, and Dissertations. Chicago Style for Students and Researchers. University Of Chicago Press.
+      Especially figure 18.1 pp 218-220 
+      NOTE: check all the details and special cases of chapter 19: "Parethetical Citations-Reference List Style: Citing Specific Types of Sources
+      I used as template the Chicago Manual of Style (Author-Date) Revision 3195
+      Code changes to adapt for a valid German version:
+      * replaced delimiter-precedes-last="always" with "never" to get rid of the last comma in author names
+      * added colon as suffix of the term "in".
+      * added colon as suffix of the termin "accessed".
+      * changed variable "issue" of "article-journal from "no." to "Nr."
+      I also changed some script logic which in noted in the code:
+      * do not add day-month at the end of a book, even it is provided in the date field of the zotero database (as it sometimes come from amazon)
+      * added access date for material with URL.
+      * not all archive items should end with a fullstop. A doi is followed by a comma and space, a URL just by a space before the date comes.
+        NOTE: this should be checked more in detail 
+      * if there is just a secondary contributor (e.g. editor of a book) then this is the primary contributor and the generated output should not repeat the name as secondary contributor.
