Permitted dictionary links

• A Stereotype can be applied (linked) to all item types.

• Most items can be linked to Comments (Applied) and Constraints (Applied).

• Most items can be linked to most other items through the Dependees link.

• You can use Tag Definitions to create links between items of types that are typically not permitted. For more information, see Overview of extending linking capabilities through stereotypes and tag definitions.

• For each item type, the table shows which items it can link to through the Links Editor, or can be linked from through a drag-and-drop operation.

• Items that have only the standard links (Comments, Constraints, Dependees and Stereotypes) are not included in the Table.
