 =head1 DESCRIPTION
 
 The B<EVP_MD> type is a structure for digest method implementation.
 It can also have associated public/private key signing and verifying
 routines.
 
-EVP_MD_meth_new() creates a new B<EVP_MD> structure. Note that B<EVP_MD>
-structures are reference counted.
+EVP_MD_meth_new() creates a new B<EVP_MD> structure.
+These B<EVP_MD> structures are reference counted.
