Purpose:MARC_LNAME is the primary argument for an XML Import validation that isolates the family name of a full name that is given in RDA format e.g:
Family Name, Given Name(s), Dates/Title etc
For instance if the incoming data was Joyce, James the word Joyce would be isolated for importing to the destination field (probably LAST_NAME).
This validation works in conjunction with MARC_FNAME, which works on the same initial data, isolating the given name.
Argument Structure: Enter MARC_LNAME as the validation. There are no further arguments.
