     # Arguments:
     # atts :: Single attribute symbol or an array of attribute symbols specifying the
     #         attribute(s) to validate.
     # Options:
-    # :allow_blank :: Whether to skip the validation if the value is blank.  You should
-    #                 make sure all objects respond to blank if you use this option, which you can do by:
-    #                     Sequel.extension :blank
+    # :allow_blank :: Whether to skip the validation if the value is blank.
     # :allow_missing :: Whether to skip the validation if the attribute isn't a key in the
     #                   values hash.  This is different from allow_nil, because Sequel only sends the attributes
     #                   in the values when doing an insert or update.  If the attribute is not present, Sequel
     #                   doesn't specify it, so the database will use the table's default value.  This is different
     #                   from having an attribute in values with a value of nil, which Sequel will send as NULL.
