 Note that concrete types are coerced "eagerly" (before the `coerce()` method returns), while interfaces are coerced "lazily" (when a property is accessed).
 
-### Required Properties
-The `Required` annotation introduced [previously](#required-parameters) can also be used to indicate that a property must contain a value. For example:
-
-```java
-public class Vehicle {
-    private String manufacturer;
-    private Integer year;
-
-    @Required
-    public String getManufacturer() {
-        return manufacturer;
-    }
-
-    public void setManufacturer(String manufacturer) {
-        this.manufacturer = manufacturer;
-    }
-
-    @Required
-    public Integer getYear() {
-        return year;
-    }
-
-    public void setYear(Integer year) {
-        this.year = year;
-    }
-}
-```
-
-Because both "manufacturer" and "year" are required, an attempt to coerce an empty map to a `Vehicle` instance would produce an `IllegalArgumentException`:
-
-```java
-var vehicle = BeanAdapter.coerce(mapOf(), Vehicle.class); // throws
-```
-
-Additionally, although the annotation will not prevent a caller from programmatically assigning a `null` value to either property, attempting to dynamically set an invalid value will generate an `IllegalArgumentException`:
-
-```java
-var vehicle = new Vehicle();
-
-var vehicleAdapter = new BeanAdapter(vehicle);
-
-vehicleAdapter.put("manufacturer", null); // throws
-```
-
-Similarly, attempting to dynamically access an invalid value will result in an `UnsupportedOperationException`:
-
-```java
-vehicleAdapter.get("manufacturer"); // throws
-```
-
-### Custom Property Names
-The `Name` annotation introduced [previously](#custom-parameter-names) can also be used with bean properties. For example:
-
-```java
-public class Person {
-    private String firstName = null;
-    private String lastName = null;
-
-    @Name("first_name")
-    public String getFirstName() {
-        return firstName;
-    }
-
-    public void setFirstName(String firstName) {
-        this.firstName = firstName;
-    }
-
-    @Name("last_name")
-    public String getLastName() {
-        return lastName;
-    }
-
-    public void setLastName(String lastName) {
-        this.lastName = lastName;
-    }
-}

+The `Required` and `Name` annotations introduced previously can also be used with bean properties.
