There is no sample xml in samples/wicked. Having schema/ppp.xml, samples/wicked/umts.xml, samples/wicked/eth0-identify.xml to view, I tried without success suchlike xml:

<interface>
  <name>ppp0</name>
  <pppoe>
    <device>eth0</device>
    <auth>
     <user>user1</user>
     <password>password1</password>
    </auth>
  </pppoe>
</interface>

Does anybody have working xml?
