/**

 * Classes for parsing and processing {@link

 * javax.xml.crypto.dsig.keyinfo.KeyInfo KeyInfo} elements and structures.

 * <code>KeyInfo</code> is an optional element that enables the recipient(s) to

 * obtain the key needed to validate an {@link

 * javax.xml.crypto.dsig.XMLSignature XMLSignature}. <code>KeyInfo</code> may

 * contain keys, names, certificates and other public key management

 * information, such as in-band key distribution or key agreement data. This

 * package contains classes representing types defined in the W3C specification

 * for XML Signatures, such as

 * {@link javax.xml.crypto.dsig.keyinfo.KeyName KeyName},

 * {@link javax.xml.crypto.dsig.keyinfo.KeyValue KeyValue},

 * {@link javax.xml.crypto.dsig.keyinfo.RetrievalMethod RetrievalMethod},

 * {@link javax.xml.crypto.dsig.keyinfo.X509Data X509Data},

 * {@link javax.xml.crypto.dsig.keyinfo.X509IssuerSerial X509IssuerSerial}, and

 * {@link javax.xml.crypto.dsig.keyinfo.PGPData PGPData}.

 * {@link javax.xml.crypto.dsig.keyinfo.KeyInfoFactory KeyInfoFactory} is an

 * abstract factory that creates <code>KeyInfo</code> objects from scratch.
