schema 16 comments: request attributes

Title: schema 16 comments: request attributes

We should be able to pass request attributes to the issuing party.

I would like to propose addition to the RequestType:

<complexType name="RequestType">

        <complexContent>

                <extension base="samlp:RequestAbstractType">

                        <sequence>

                                <element ref="saml:Attribute" minOccurs="0" maxOccurs="unbounded"/>

                                <choice>

                                        -- same as before --

                                </choice>

                        <sequence>

                </extension>

        </complexContent>

</complexType>
