<p>The KeyName element contains a string value (in which white space is
significant) which may be used by the signer to communicate a key
identifier to the recipient. Typically, KeyName contains an identifier
related to the key pair used to sign the message, but it may contain
other protocol-related information that indirectly identifies a key pair.
(Common uses of KeyName include simple string names for keys, a key index,
a distinguished name (DN), an email address, etc.)</p>

A RetrievalMethod element within KeyInfo is used to convey a reference to
KeyInfo information that is stored at another location. For example,
several signatures in a document might use a key verified by an X.509v3
certificate chain appearing once in the document or remotely outside the
document; each signature's KeyInfo can reference this chain using a single
RetrievalMethod element instead of including the entire chain with a
sequence of X509Certificate elements.</p>
<p>RetrievalMethod uses the same syntax and dereferencing behavior as
Reference's URI and The Reference Processing Model.</p>

the originator to a known recipient(s). It may be used as a stand-alone
XML document, be placed within an application document, or appear inside
an EncryptedData element as a child of a ds:KeyInfo element. The key value
is always encrypted to the recipient(s). When EncryptedKey is decrypted the
resulting octets are made available to the EncryptionMethod algorithm
without any additional processing.</p>
