EA_OnPreNewAttribute notifies Add-Ins that a new attribute is about to be created on an element. It enables Add-Ins to permit or deny creation of the new attribute.
This event occurs when a user creates a new attribute on an element by either drag-dropping from the Browser window, using the 'Attributes' tab of the Features window, or using the in-place editor on the diagram. The notification is provided immediately before the attribute is created, so that the Add-In can disable addition of the attribute.
