When {{cs1}} and {{cs2}} templates contain {{para|citeseerx}}, a test is done to see if the [[CiteSeerX]] identifier has the proper format.
The expected identifier is the value assigned to the <code>?doi=</code> query key in the URL of a CiteSeerX document. (This query key should not be confused with a [[Digital Object Identifier]]: it should not be input as {{para|doi}}.)

For instance, if you want to link to <code>http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.220.7880</code>, use {{para|citeseerx|10.1.1.220.7880}}.
