Where are the predefined icons in the SDK?

Looking through the documentation on the VMware Developer Center (vSphere UX Design section) under "Icons" (http://developercenter.vmware.com/web/standards/-/icons), it states:

     The SDK provides pre-defined icons for common actions, such as "edit" and "delete."

     Pre-defined in the SDK, message icons are provided in two sizes:  the 32 x 32 pixel icon is for use in a message dialog, while the 16 x 16 pixel icon is for messages that appear directly in the UI.

I downloaded the 5.5 SDK and cannot find the icons.  I found a few in the samples, such as the "edit" and "delete", but not any of the others mentioned in the documentation.

Am I looking in the right place?

Thanks for any help provided,

Steve
