Indicates whether or not the contributor is the corresponding contributor for the content.
Although many journals specify only one corresponding author, in other journals there is no limit to the number of contributors who may be designated to receive correspondence for the article. Accordingly, more than one <contrib> element may have its @corresp attribute set to “yes”.
|no||This author (or other contributor) is not a corresponding author.|
|yes||This author (or other contributor) is a corresponding author.|
