Administrators can remove Attributes of any Type from the Dynamic Evidence Type Version.
This is achieved by clicking the 'x' button which appears in the top left-hand corner of the Attribute in the Evidence class on the Model Canvas.
Note: Similar to changing the Type of a Data Attribute or Calculated Attribute, if the Attribute being deleted is currently referenced in Validations, Summary Information, Business Start and End Dates, Related CP Properties, or has a Field in respect of it in the User Interface, the Editor will confirm if the administrator still wants to delete them. If the administrator confirms the delete, the Editor will proceed to remove all traces of the deleted Attribute from the Dynamic Evidence Type Version (e.g. by blanking out Business Start and End Dates, by removing Validations which reference it, by removing User Interface components which reference it, etc.)
