There are a large number of possible Properties that can be added to ENTITY files within the TkAttachmentData Property. Pretty much all of the Properties that can be used end with ComponentData.

This will be a work in process for a while due to the large number of Properties available for use.
See this entity reference list for a more detailed list of what is useable.
