An XML file is prepared using the CustomTypeEditor.exe utility that can be found in <Intellect installation directory>\Tools. The utility overview is shown below.

An XML file for a virtual object is created as follows:

1. Specify the name of object type in the object_type field (1).
   
2. Specify the name of parent type in the parent_type field (2).
3. If the object type has child types, then set the has_child checkbox checked (3).
4. Repeat steps 1-3 for all object types.
5. Save a file with any name in the Intellect installation directory using the File – Save command.

The XML file is now created. The file contents look like this:

<?xml version="1.0" standalone="yes"?>

<objects>

<object>

<object_type>CUSTOM</object_type>

<parent_type>SLAVE</parent_type>

<has_child>1</has_child>

</object>

<object>

<object_type>CUSTOM_CHILD</object_type>

<parent_type>CUSTOM</parent_type>

</object>

</objects>

Modify it manually if required.

In particular, you can add a parameter <include_parent_id>1</include_parent_id> for the object. When setting this parameter to 1, the IDs of the child virtual objects will include the ID of the parent object. For example, if the CUSTOM object has a child CUSTOM_CHILD, and the CUSTOM has ID = 3, then CUSTOM_CHILD objects will be created with the identifiers 3.1, 3.2, etc.
