# Additional Parameters

Apart from regular requested attributes, the AuthnRequest to Signicat may contain additional parameters in the Extensions in the form of RequestedAttributes. To process these, the name of the RequestedAttribute should be of the form signicat:param:parametername. These can optionally contain a string type value.

<samlp:Extensions>
        <req-attr:RequestedAttributes>
            <md:RequestedAttribute isRequired="true"
                                   Name="firstName"
                                   NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"/>
            ...
            <md:RequestedAttribute isRequired="true"
                                   Name="signicat:param:additional-param">
                <saml:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                                     xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:string">Additional param
                </saml:AttributeValue>
            </md:RequestedAttribute>
            <md:RequestedAttribute isRequired="false"
                                   Name="signicat:param:additional-param1">
            </md:RequestedAttribute>
