I would like to bind the text of XamScreenTips to a sting in the command for the related ButtonTool. This will allow me to display messages in the screen tip when a user rolls over a disabled button that would explain why it is disabled (ie: 'You need admin permissions to use this').

I am using an ICommand with a DisabledMessage string for the command of the ButtonTools. I also took the default XamScreenTip control template and build upon it to add styling and triggers to hide the footer when a button is enabled. Is there a way from within the XamScreenTip control template to reference the related ButtonTool and its command string?
