Missing documentation for CF_PLACEHOLDER_MANAGEMENT_POLICY

This docs-page https://learn.microsoft.com/en-us/windows/win32/api/cfapi/ns-cfapi-cf_sync_policies includes a reference to CF_SYNC_MANAGEMENT_POLICY, but there is no page or any comment to what that actually does.
The native enum isn't even included anywhere:

typedef enum CF_PLACEHOLDER_MANAGEMENT_POLICY {  
    CF_PLACEHOLDER_MANAGEMENT_POLICY_DEFAULT          = 0x00000000,  
    CF_PLACEHOLDER_MANAGEMENT_POLICY_CREATE_UNRESTRICTED     = 0x00000001,  
    CF_PLACEHOLDER_MANAGEMENT_POLICY_CONVERT_TO_UNRESTRICTED = 0x00000002,  
    CF_PLACEHOLDER_MANAGEMENT_POLICY_UPDATE_UNRESTRICTED     = 0x00000004,  
} CF_PLACEHOLDER_MANAGEMENT_POLICY;
