+=head2 OSSL_STORE Method
+
+B<X509_LOOKUP_store> is a method that allows access to any store of
+certificates and CRLs through any loader supported by
+L<OSSL_STORE(3)>.
+It works with the help of URIs, which can be direct references to
+certificates or CRLs, but can also be references to catalogues of such
+objects (that behave like directories).
+
+This method overlaps the L</File Method> and L</Hashed Directory Method>
+because of the 'file:' scheme loader.
+It does no caching of its own, but can use a caching L<OSSL_STORE(3)>
+loader, and therefore depends on the loader's capability.
