I have developed an app using Silverlight XNA, with AdDuplex (for Silverlight 1.2.3) and Scoreloop (Core Social 1.2.0).
I have defined capabilities of my app in WMAppManifest.xml as
<Capabilities>
    <Capability Name="ID_CAP_NETWORKING"/>
    <Capability Name="ID_CAP_MEDIALIB"/>
    <Capability Name="ID_CAP_IDENTITY_DEVICE"/>
</Capabilities>`
and every function works properly. (Sorry I do not know how to type in < here. Please help me edit it.)
However, after I submitted it, it shows in App Hub as
Required Device capabilities
data services 
music and video library
web browser 
owner identity 
XNA framework 
Silverlight framework 
phone identity 
trial 
Though I later run the Markeplace Test Kit, it shows the same thing.
My question are:
Where do owner identity and web browser come from?
Why does App Hub override my decision?
