BorderContainer Skin File is somehow empty

Question

Hi

When i generate skin files lets suppose for s:Button, they contain all the design related code such as graphic, label etc, but when i create a skin file of BorderContainer, it gets created without any design code and event the contentGroup part is commented and i dont know how to use it.

Could you please guide me how to custimize its skin file?

<?xml version="1.0" encoding="utf-8"?>

[HostComponent("spark.components.BorderContainer")]

<!-- states -->
<s:states>
    <s:State name="disabled" />
    <s:State name="normal" />
</s:states>

<!-- SkinParts
name=contentGroup, type=spark.components.Group, required=false
-->
