Package oid defines OIDs for different CSPs. Currently this is used in attested TLS to distinguish the attestation documents.
OIDs beginning with 1.3.9900 are reserved and can be used without registration.

* The 1.3.9900.1 branch is reserved for placeholder values and testing.

* The 1.3.9900.2 branch is reserved for AWS.

* The 1.3.9900.3 branch is reserved for GCP.

* The 1.3.9900.4 branch is reserved for Azure.

* The 1.3.9900.5 branch is reserved for QEMU.

Deprecated OIDs should never be reused for different purposes.
Instead, new OIDs should be added in the appropriate branch at the next available index.
