This allows // you to keep information in an ACL that can be retrieved later. In particular, // you can "prefix" any external ACL subject representation with an ACL_COMMENT // header, which turns it into an inactive comment until you remove the prefix. // // Notes: // (1) All contents of a comment ACL are public. // (2) While there is a COMMENT sample type, it is in no way related to this subject // type. Validation of a COMMENT acl subject never examines any samples. // #ifndef _ACL_COMMENT #define _ACL_COMMENT #include namespace Security { // // The ANY subject simply matches everything.
