- * FIXME:
- * - As you can see in the stubs below, support for CRLs and CTLs is missing.
- * Mostly this should be copy-paste work, and some code (e.g. extended
- * properties) could be shared between them.
- * - Opening a cert store provider should be morphed to support loading
- * external DLLs.
- * - The concept of physical stores and locations isn't implemented. (This
- * doesn't mean registry stores et al aren't implemented. See the PSDK for
- * registering and enumerating physical stores and locations.)
- * - Many flags, options and whatnot are unimplemented.
