The Adobe doc Developing AIR applications for mobile devices lists quite a few icons to be declared in an application descriptor file.

But when I try Export Release Build with the following myApp-app.xml:

<icon>
    <image16x16>assets/icons/16x16.png</image16x16>
    <image29x29>assets/icons/29x29.png</image29x29>
    <image32x32>assets/icons/32x32.png</image32x32>
    <image36x36>assets/icons/36x36.png</image36x36>
    <image48x48>assets/icons/48x48.png</image48x48>
    <image57x57>assets/icons/57x57.png</image57x57>
    <image72x72>assets/icons/72x72.png</image72x72>
    <image114x114>assets/icons/114x114.png</image114x114>
    <image128x128>assets/icons/128x128.png</image128x128>
    <image512x512>assets/icons/512x512.png</image512x512>
    <!-- 
    <image50x50>assets/icons/50x50.png</image50x50>
    <image58x58>assets/icons/58x58.png</image58x58>
    <image100x100>assets/icons/100x100.png</image100x100>
    <image144x144>assets/icons/144x144.png</image144x144>
    <image1024x1024>assets/icons/1024x1024.png</image1024x1024>
     -->
</icon>

I get the error message (regardless if deploying for Android or iOS) unless I comment the 5 lines as above:

error 103: application.icon.image50x50 is an unexpected element/attribute
error 103: application.icon.image58x58 is an unexpected element/attribute
error 103: application.icon.image100x100 is an unexpected element/attribute
error 103: application.icon.image1024x1024 is an unexpected element/attribute
error 103: application.icon.image144x144 is an unexpected element/attribute

My question is what to do here? Moving those 5 icons underneath <android>....</android> or <iphone>....</iphone> doesn't help either.
