I've installed STS on MacOS 10.8.2. I am wondering how to add Spring XSD namespaces to the XSD Namespaces so they appear in the XSD Namespace Selection dialog when using the "New Spring Bean Configuration File" from the New context menu.

I reached this dialog selecting New -> Spring Bean Configuration File -> Next button. A Screenshot of the dialog I am mentioning is below.
