/**
* <p>This class represents a scope for identities. It is an Identity itself,
* and therefore has a name and can have a scope. It can also optionally have a
* public key and associated certificates.</p>
*
* <p>An <code>IdentityScope</code> can contain {@link Identity} objects of all
* kinds, including {@link Signer}s. All types of <code>Identity</code> objects
* can be retrieved, added, and removed using the same methods. Note that it is
* possible, and in fact expected, that different types of identity scopes will
* apply different policies for their various operations on the various types of
* <code>IdentityScope</code> represents a scope of an identity.
* <code>IdentityScope</code> is also an {@link Identity} and can have a name
* and scope along with the other qualitites identities possess.
*
* <p>An <code>IdentityScope</code> contains other {@link Identity} objects.
* All {@link Identity} objects are manipulated in the scope the same way. The
* scope is supposed to apply different scope to different type of
* Identities.</p>
*
* <p>There is a one-to-one mapping between keys and identities, and there can
* only be one copy of one key per scope. For example, suppose Acme Software,
* Inc is a software publisher known to a user. Suppose it is an <i>Identity</i>,
* that is, it has a public key, and a set of associated certificates. It is
* named in the scope using the name "Acme Software". No other named <i>Identity
* </i> in the scope has the same public key. Of course, none has the same name
* as well.</p>
*
*
* <p>No identity within the same scope can have the same public key.</p>
