Analysis exception processing SPDX file: Can not add relationshps to an ExternalSpdxElement. 
These changes must be done to the local SPDX element in the document which defines the SPDX element.

Who is right?

Preventing writes to the external element is intentional. A couple of thoughts:

• In SPDX 2.X, the relationship is a property of the Element. Since the relationships are serialized along with the Element, we should not allow updates since they can not be written out.
• In SPDX 3.X, relationships are not properties of the Element, they are stand-alone elements with a to and from property - so they can be "added" independent of the Element. We will be able to add relationships to external elements only for the 3.X spec versions - once the code for SPDX 3.X is complete.
