The 'Internal' group of attributes is hidden from the user and is only encountered if working with the XML source of a saved TBX file. This group cannot be accessed via the UI, such as via the documents Inspector/System tab. Do note attempt to export or use action script on these items. The group is comprised of following known attributes:
- $Alias. Boolean type. Marks if an object is an alias. Appears to be mapped by the visible attribute $IsAlias.
- $EntryScript. String type. Purpose undocumented.
- $ExitScript. String type. Purpose undocumented.
- $WindowPlace. [Unknown] type. Purpose undocumented, but may be used to seed values for individual window position/state stored in the TBX.
