If you use the Select DTD command on the Objects menu to select a different document type definition file, different or additional object types and attributes may appear in the Object info dialog box. (See Select DTD.)

For example:

If you select webcgm21 in the Select DTD dialog box, the additional visibility and interactivity attributes appear.

If you select catalog in the Select DTD dialog box, and then select part in the Object type field in the Object info dialog box, a list of several additional attributes appears.

To enter a value for an attribute in the list, click the attribute name and then enter the value in the box to the right of the list.
