The System attributes' groups, as defined in a default TBX, include an 'Internal' group. This group of attributes are not exposed via the Tinderbox user interface but appear to be a standard part of the TBX document defaults for internal use via the app. The exact purpose of all the following is unknown and users should not attempt to use or alter these:
- $GeocodeAddress. New in v6.
- $WindowPlace. Likely used in v5 but not v6.
