/*
Authentication assertions provided in an <AuthnResponse> element MUST be of
type AssertionType, which is an extension of saml:AssertionType, so that the
RequestID attribute from the original <AuthnRequest> MAY be included in the
InResponseTo attribute in the <Assertion> element. This is done because it is
not required that the <AuthnResponse> element itself be signed. Instead, the
individual <Assertion> elements contained MUST each be signed. Note that it is
optional for the InResponseTo to be present. Its absence indicates that the
<AuthnResponse> has been unilaterally sent by the identity provider without a
corresponding <AuthnRequest> message from the service provider. If the
attribute is present, it MUST be set to the RequestID of the original
<AuthnRequest>.

The schema fragment is as follows:

<xs:element name="Assertion" type="AssertionType" substitutionGroup="saml:Assertion" />
<xs:complexType name="AssertionType">
  <xs:complexContent>
    <xs:extension base="saml:AssertionType">
      <xs:attribute name="InResponseTo" type="xs:NCName" use="optional"/>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>
