 ```golang
 type Person struct {

-	Emails []string `checkers:"@max-len:1 max-len:4"`
+	Emails []string `checkers:"@max-len:2 max-len:64"`
 }
 ```
 
 In this example:
-- `@max-len:1` ensures that the `Emails` slice itself has at most one item.
-- `max-len:4` ensures that each email string within the `Emails` slice has a maximum length of 4 characters.
+- `@max-len:2` ensures that the `Emails` slice itself has at most two items.
+- `max-len:64` ensures that each email string within the `Emails` slice has a maximum length of 64 characters.
