+# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
+# These types are mapped to the appropriate JSON type.
+#
+# 2) A legacy type in the form 'legacy<subtype>' where subtype is the
+# legacy qdev typename. These types are always treated as strings.
+#
+# 3) A child type in the form 'child<subtype>' where subtype is a qdev
+# device type name. Child properties create the composition tree.
+#
+# 4) A link type in the form 'link<subtype>' where subtype is a qdev
+# device type name. Link properties form the device model graph.

+# Since: 1.1
+#
+# Notes: This type is experimental. Its syntax may change in future releases.
