In this example execution two Verifiable Credentials associated with a single Holder are issued and then

combined into a single Verifiable Presentation.

The Verifiable Credentials are of two different models. The use-case is meant to mimic
|
|
- Holder being a physical person,
|
|
- Issuer A being "Pare Manel" foundation,
|
|
- Issuer B being "EXO" foundation,
|
|
- Verifier (not pictured) being "Som Connexio", which wants verifiable data of the Holder from both Issuers.
