How to set default page layout

Question

I have created a site definition, when creating a subsite my layout that I want to use doesn't get set?

How can I set my own default page layout when creating a subiste?

Here is my onet.xml

Doing like this doesn't change my default publishing page layout

<Modules>
<Module Name="MyDef" Url="$Resources:osrvcore,List_Pages_UrlName;" Path="">
  <File Url="default.aspx" >
    <Property Name="Title" Value="$Resources:cmscore,IPPT_HomeWelcomePage_Title;" />
    <Property Name="PublishingPageLayout" Value="~SiteCollection/_catalogs/masterpage/FSF_Avdelningsplats_Elmia.aspx, $Resources:cmscore,PageLayout_WelcomeLinks_Title;" />
    <Property Name="ContentType" Value="$Resources:cmscore,contenttype_welcomepage_name;" />
  </File>
</Module>

You can set that in the publishing feature itself in onet.xml, basically in the publishing feature inside you web features, you should do something like this:

<WebFeatures>
 <Feature ID='Id for publishing feature'>
   <Properties xmlns="http://schemas.microsoft.com/sharepoint/">
    <Property Key="DefaultPageLayout" Value="~SiteCollection/_catalogs+masterpage/MyPageLayout.aspx"/>
   </Properties>
    </Feature>
    <!-- Other web features..-->    
</WebFeatures>
