There is no an ability to set an exact ordering for the items of a dependency injection's argument of type «array»

There is no an attribute like ordering here:

magento/magento2/blob/2.1.6/lib/internal/Magento/Framework/Data/etc/argument/types.xsd#L14-L27


<xs:complexType name="array" mixed="true">
    <xs:complexContent>
        <xs:extension base="argumentType">
            <xs:sequence>
                <xs:element name="item" type="argumentType" minOccurs="0" maxOccurs="unbounded">
                    <xs:key name="itemName">
                        <xs:selector xpath="item"></xs:selector>
                        <xs:field xpath="@name"></xs:field>
                    </xs:key>
                </xs:element>
            </xs:sequence>
        </xs:extension>
    </xs:complexContent>
</xs:complexType>

So there is no an ability to set an exact ordering, e.g., for the checkout configuration providers (configProviders):

github.com

magento/magento2/blob/f1033b26/app/code/Magento/Checkout/etc/frontend/di.xml#L46-L53


<type name="Magento\Checkout\Model\CompositeConfigProvider">
    <arguments>
        <argument name="configProviders" xsi:type="array">
            <item name="checkout_default_config_provider" xsi:type="object">Magento\Checkout\Model\DefaultConfigProvider</item>
            <item name="checkout_summary_config_provider" xsi:type="object">Magento\Checkout\Model\Cart\CheckoutSummaryConfigProvider</item>
        </argument>
    </arguments>
</type>
