# iFS XML Syntax Reference

This reference lists the XML syntax for the items most commonly created by administrators and developers in iFS.

The links in the table of contents at left will display the XML attributes for each of the objects listed, with information about the datatype of each attribute, and whether it is required, optional, or set by the system automatically.

Required attributes must be set in the XML definition file in order to create the object. Failure to set the attribute will result in an error.

Optional attributes allow you to set additional properties in your XML definitions. If you choose not to set these attributes, they can be omitted from your XML definition.

System Set attributes are set automatically by iFS, and cannot be modified. They are provided here for your reference.
