Adding "saml" namespace to MetadataProvider

[Michael A Grady]

FYI, so that strategies like this ( https://spaces.at.internet2.edu/x/gYA5CQ ) work, and entity attribute filter rules in general, I think you want to add (you may already have done so) the saml namespace definition by default into the provided metadata-providers.xml file with the IdP distribution. I.e. adjust it to something like this:

<MetadataProvider id="ShibbolethMetadata" xsi:type="ChainingMetadataProvider"
    xmlns="urn:mace:shibboleth:2.0:metadata"
    xmlns:resource="urn:mace:shibboleth:2.0:resource"
    xmlns:security="urn:mace:shibboleth:2.0:security"
    xmlns:md="urn:oasis:names:tc:SAML:2.0:metadata"
    xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="urn:mace:shibboleth:2.0:metadata http://shibboleth.net/schema/idp/shibboleth-metadata.xsd
                        urn:mace:shibboleth:2.0:resource http://shibboleth.net/schema/idp/shibboleth-resource.xsd 
                        urn:mace:shibboleth:2.0:security http://shibboleth.net/schema/idp/shibboleth-security.xsd
                        urn:oasis:names:tc:SAML:2.0:assertion http://docs.oasis-open.org/security/saml/v2.0/saml-schema-assertion-2.0.xsd
                        urn:oasis:names:tc:SAML:2.0:metadata http://docs.oasis-open.org/security/saml/v2.0/saml-schema-metadata-2.0.xsd">

p.s. I did add a comment to the bottom of that wiki page noting one needed to add the saml namespace definition in order for the example to work.
