What are the best practices for representing XSD complex types in PHP classes?

When representing XSD complex types in PHP classes, it is important to map the XSD structure to PHP classes accurately. This involves creating PHP classes that mirror the structure of the XSD complex types, including properties for each element or attribute defined in the XSD. Additionally, it is recommended to use inheritance and composition to represent complex types with nested elements or attributes.

// Example of representing XSD complex type in PHP class

class Person {
    public $name;
    public $age;
}

// Example of representing XSD complex type with nested elements in PHP class

class Address {
    public $street;
    public $city;
}

class Contact {
    public $email;
    public $phone;
    public $address; // Composition of Address class
}
