 ### Explicit constraint syntax
 
-EVFL also supports the ability to define constraints explicitly. This can be particular useful
+Constraints can also be expressed explicitly. This can be particular useful
 when it is otherwise not possible to express a layout or rule:
 
-    C:view1.centerX(view2.centerX)   // view1 is horizontally centered to view2
-    C:view1.centerY(view2)           // view1 is vertically centered to view2 (centerY is derived for view2)
-    C:view1.centerX(view2).bottom(view2.bottom) // view1 is horizontally centered and bottom aligned toview2 (chaining syntax)
+    C:view1.centerX(view2.centerX)     // view1 is horizontally centered to view2
+    C:view1.centerX(view2)             // attribute is inferred when omitted (centerX)
+    C:view1.centerX(view2).bottom(view2.bottom) // chaining syntax
+    C:view1.height(view2.width*2+10)   // expressions
