Translator fetches journal articles and cases (new) from Juris

Okay. I will try to implement that.
I see a problem with using "title" for caseName, still. As mentioned above, only few cases have case names. Currently, in my CSL, I test the variable "references" (Zotero.history). If it is set, it contains the case name which I can append to the citation. If it is empty, no case name is appended.
Now, title will always be set (Zotero enforces it), so I do not see a way to distinguish whether there is a case name or not. Any idea?
