How to sort footer links via XML in Magento2

Question

Referencing to this ticket: Magento 2 - Remove and change footer links

I have now the question if one can change the position from the respective links without removing them and reinitiating them afterwards.

Is there any sort parameter for XML?

<referenceBlock name="catalog-search-advanced-link" remove="true"/>
<referenceBlock name="search-term-popular-link" remove="true"/>
<referenceBlock name="sales-guest-form-link" remove="true"/>

<referenceBlock name="footer_links">
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="ueber-uns">
            <arguments>
                <argument name="label" xsi:type="string">Über uns</argument>
                <argument name="path" xsi:type="string">ueber-uns</argument>
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="kundenservice">
            <arguments>
                <argument name="label" xsi:type="string">Kundenservice</argument>
                <argument name="path" xsi:type="string">customer-service</argument>
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="contact-us-link">
            <arguments>
                <argument name="label" xsi:type="string">Kontakt</argument>
<!--                 <argument name="path" xsi:type="string">customer-service</argument> -->
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="privacy-policy-link">
            <arguments>
                <argument name="label" xsi:type="string">Datenschutz</argument>
            </arguments>
        </block>
    </referenceBlock>

Results in:

Datenschutz
Kontakt
Über uns
Kundenservice

on the frontend (in this order), even if I declared "Über uns" BEFORE I changed the name of the contact-us-link and the privacy-policy-link

Just keep in default.xml file like below,

Using After and Before tag of xml you can use before or after element. before="-" means current block display before all other elements in its parent node.`

after="-" means current block display after all other elements in its parent node.

In our case parent node is footer_links based on this block before and after attributes are set.

<referenceBlock name="footer_links">
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="ueber-uns" after="contact-us-link">
            <arguments>
                <argument name="label" xsi:type="string">Über uns</argument>
                <argument name="path" xsi:type="string">ueber-uns</argument>
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="kundenservice" after="ueber-uns">
            <arguments>
                <argument name="label" xsi:type="string">Kundenservice</argument>
                <argument name="path" xsi:type="string">customer-service</argument>
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="contact-us-link" after="privacy-policy-link">
            <arguments>
                <argument name="label" xsi:type="string">Kontakt</argument>
<!--                 <argument name="path" xsi:type="string">customer-service</argument> -->
            </arguments>
        </block>
        <block class="Magento\Framework\View\Element\Html\Link\Current" name="privacy-policy-link" before="-">
            <arguments>
                <argument name="label" xsi:type="string">Datenschutz</argument>
            </arguments>
        </block>
    </referenceBlock>
