+# @DevicePropertyInfo:
+#
+# @name: the name of the property
+#
+# @type: the type of the property.  This will typically come in one of four
+#        forms:
+#
+#        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.
