Adding Custom WebPart in AllUsersWebPart in SharePoint 2013

Hi 

I am trying to add the Custom WebPart to Custom PageLayout using 

AllUsersWebPart.
But the webpart is not adding to the page when created.
 The same code if i am adding to Pages 
AllUsersWebPart , its coming.
Is there any thing need to do with PageLayout AllUsersWebPart property
  <![CDATA[              
        <?xml version="1.0" encoding="utf-8"?>
        <webParts>
          <webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
            <metaData>
              <type name="SolutionX.ProjectY.WebParts.MyWebPart, $SharePoint.Project.AssemblyFullName$" />
              <importErrorMessage>$Resources:core,ImportErrorMessage;</importErrorMessage>
            </metaData>
            <data>
              <properties>
                <property name="Title" type="string">My WebPart</property>
                <property name="Description" type="string">My WebPart for XYZ</property>
                <property name="ListName" type="string">ExampleList</property>
                <property name="RowLimit" type="string">5</property>
              </properties>
