A package-level relationship defines an association between the package and an associated target part or resource. A package-level relationship can be one of two forms.

  • Between a Package to a target part in the package.

  • Between a Package to a target resource outside the package.

In a package-relationship the package is considered the "owner" of the relationship. When the package is deleted, all the relationships owned by the package are also deleted.

No exception is raised if a relationship with the specified id is not in the package.

DeleteRelationship does not physically change the target part in any way.
