Smart Tag components are available in the tagdictionary palette.
You can add smart tag components to a tag dictionary by dragging them to the tag definitions list, and then drag them onto individual components using the Edit Tags dialog box. However, the tags would not be implied, only included in the tag definitions list. To be implied, the smart tags must be included in the tag lists of tag rules. As a rule, these tags are more effectively applied by including them in the tag lists of tag rules.
