buttonNamespace Element 

<buttonNamespace> Element

Namespace in which the button functions. For example,

<buttonNamespace>microsoft.windowslive</buttonNamespace>

Attributes

None

Remarks

Optional, but strongly recommended. A button may have one <buttonNamespace> element.

The namespace and the name of the button cabinet file combine to form the name of the install directory for the button. For example, if the button defined by weather.btn uses the namespace live.com, the button is installed in the directory live.com.weather. This mechanism helps avoid naming collisions.
