cs1|2 templates cite single sources; when the identifiers in |doi=, |id=, and |page= are different from each other then the template is attempting to cite multiple sources. This function evaluates the identifier portions of these parameters. returns seven values: identifyier parts (or nil when parameter not used) and a message (nil on success, error message else)

the identifier portions of the several parameters must be properly formed
