QoS in PAP

[Zohar]

I sent a push message with the following element in the PAP:   <quality-of-service priority="high" network="" network-required="false" bearer="" bearer-required="false"/>   The PPG replied with:   <?xml version="1.0"?> <!DOCTYPE pap PU BLIC "-//WAPFORUM//DTD PAP 1.0//EN" "http://www.wapforum.org/DTD/pap_1.0.dtd"> <pap>  <badmessage-response code="2000" desc="Not understood due tomalformed syntax" bad-message-fragment="&lt;?xml version=&quot;1.0&quot;?&gt;..&lt;!DOCTYPE papPUBLIC &quot;-//WAPFORUM//DTD PAP 1.0//EN&quot;&quot;http://www.wapforum.org/DTD/pap_1.0.dtd&quot;&gt;..&lt;pap&gt;..&lt;push-message push-id=&quot;31674/982/Openwave Push&quot;&gt;..&lt;address address-value=&quot;WAPPUSH=192.118.11.113/[EMAIL PROTECTED]&quot;/&gt;.&lt;quality-of-service network=&quot;&quot; network-required=&quot;false&quot; bearer=&quot;&quot; bearer-required=&quot;false&quot;/&gt;.&lt;/push-message&gt;..&lt;/pap&gt;"/> </pap>   Why did it fail?
