-A ``KeyLocator`` specifies either a name that points to another Data packet containing certificate or public key or ``KeyDigest`` to identify the public key within a specific trust model (the trust model definition is outside the scope of the current specification).
+A ``KeyLocator`` specifies either ``Name`` that points to another Data packet containing certificate or public key or ``KeyDigest`` to identify the public key within a specific trust model (the trust model definition is outside the scope of the current specification).
 Note that although ``KeyLocator`` is defined as an optional field in ``SignatureInfo`` block, some signature types may require presence of it and some require ``KeyLocator`` absence.
