Here are some reasons why a collection (and not a single certificate) might be needed:

1. Certificate Chains
   • In many cases, a single certificate is not enough to establish a trust relationship. A certificate chain, which includes intermediate certificates leading up to a root certificate, might be required. The collection allows you to provide the entire chain.
   • Including the root certificate in the collection can help in scenarios where the root certificate is not already trusted by the client or server.
2. Multiple Identities
   • A client might need to present different certificates for different services or endpoints. Having a collection allows the client to choose the appropriate certificate based on the server's request.
   • Some protocols or services might require the client to present multiple certificates for different purposes, such as signing and encryption.
3. Fallback Mechanisms
   • In some cases, a primary certificate might fail or be invalid. Having a collection allows the client to fall back to a secondary certificate without requiring a new connection setup.
