Most of the elements can be created in one of the approaches listed in Instantiating an element. However, sub type elements are not created in those ways:

The tag name arguments is reserved for ElementFactory. When you want to invoke a method against something, you need to define arguments as the input for the method.

For example, in order to call constructor method of SimpleElement public SimpleElement(String a, int b, String c), you need to define the arguments as follows:

For each element in the arguments, you need to define an attribute ArgumentType, which is the type of argument in the method declaration; and the sub-elements needs to be exactly in the sequence of the arguments in the method declaration. This principle also applies to instantiating element by static factory and instance factory.

The element entry is used to define entries in a java.util.Map. The tag name entry is also reserved. See Defining collections.

There are some built-in data types in Java language that cannot be instantiated by default constructor, constructor, static factory or instance factory. They are treated as simple elements and the ElementFactory can handle them.

The following table lists all the supported simple elements and the sample definitions.
