Use XSD description in DMR description, because description in XSD is better for attributes

• provider-name
• providers
• other-providers
• relative-to
• uri (DMR description contains wrong vault://)

For type attribute use this description in both XSD and DMR: "The credential store type, e.g. KeyStoreCredentialStore" . Now there is mentioned wrongly KeyStorePasswordStore

        <xs:attribute name="type" type="xs:string" use="optional">
            <xs:annotation>
                <xs:documentation>
                    The credential store type, e.g. KeyStorePasswordStore.
                </xs:documentation>
            </xs:annotation>
        </xs:attribute>
