Thank you for your feedback, Ard Biesheuvel. After reviewing the UEFI Specification our interpretation is that because it is now optional to support any of the EFI Runtime Services, the EFI_RT_PROPERTIES_TABLE needs to be published for the caller at runtime to know which runtime services have been implemented.
What we are testing in this patch is whether the EFI_RT_PROPERTIES_TABLE has been installed and whether the RuntimeServicesSupported value has been populated to reflect which optional runtime services are implemented. > > 34.
