<null/>
Boolean true bool true
<true/>
Boolean false bool false
<false/>
String string

Array (elements
can be mixed
types)
A collection
that allows
mixed-type
elements, such
as ArrayList or
object[]
<array>
<property id="0">
<number>27.5</number>
</property>
<property id="1">
<string>Hello there!</string>
</property>
...
</array>
The <property>
node defines
individual
elements, and the
id attribute is the
numeric, zero-
based index.
Object A dictionary
with string keys
and object
values, such as
a HashTable
with string keys
<object>
<property id="name">
<string>John Doe</string>
</property>
<property id="age">
<string>33</string>
</property>
...
</object>
The <property>
node defines
individual
properties, and the
id attribute is the
property name (a
string).
Other built-in or
custom classes
<null/>
or
<object></object>
ActionScript
encodes other
objects as null or
as an empty
object. In either
case any property
values are lost.
