Hi,
Got it. Then, I imagine that you could create your own XBL controls for each button, which would mostly be copies of button.xbl. But I don't like the idea that you'd need to copy button.xbl, just to avoid typing "Save" or "Edit". Maybe you could create a single control that uses the xf:trigger and allows the user to select the value of the label from a dropdown in the control properties. I think that would be my prefered way of doing this.
