     This boundary condition is similar to the cyclic condition, except that
     it is applied to 2-D geometries.
 
-    The "value" entry is NO_READ, NO_WRITE.
+    The "value" entry is MUST_READ.
 
 Usage
     Example of the boundary condition specification:
     \verbatim
     <patchName>
     {
-        type            wedge;
+        type    wedge;
