/**
 * lasso_saml_audience_restriction_condition_new:
 * 
 * Creates a new <saml:AudienceRestrictionCondition> node object.
 * 
 * The <AudienceRestrictionCondition> element specifies that the assertion is
 * addressed to one or more specific audiences identified by <Audience>
 * elements. Although a party that is outside the audiences specified is
 * capable of drawing conclusions from an assertion, the issuer explicitly
 * makes no representation as to accuracy or trustworthiness to such a party.
 *
 * The AudienceRestrictionCondition evaluates to Valid if and only if the
 * relying party is a member of one or more of the audiences specified. The
 * issuer of an assertion cannot prevent a party to whom it is disclosed from
 * making a decision on the basis of the information provided. However, the
 * <AudienceRestrictionCondition> element allows the issuer to state explicitly
 * that no warranty is provided to such a party in a machine- and
 * human-readable form. While there can be no guarantee that a court would
 * uphold such a warranty exclusion in every circumstance, the probability of
 * upholding the warranty exclusion is considerably improved.

 * Return value: the new @LassoSamlAudienceRestrictionCondition
