=====================================================
Feature Description
Support for interaction with a secure world should be done to allow programs desiring to hold secrets from other programs to be ported.

Feature Benefits
List the reasons why this feature would be beneficial

• Allows for certain proprietary programs to be ported easier, such as web browsers with certain extensions. This, of course, requires the program's developer to port the program in the first place however.
• More broad hardware support when ports should be done
• Allows for system management that system escalation won't simply bypass. Ie, a secure way to hold onto filesystem access permissions.

Use case examples
List examples where this feature could be useful for end users.

• Programs requiring secure services will be possible to port
• The system may now have hardware allow for protection against unauthorized accessing of files, ie, protecting a user's home directory from being viewed by others based on permissions granted by the secure world
• Additional utilization of hardware
