The Action of a User requesting an Export-Import Service to:
1. Render an Item MM-Embedded at an M-Location with a Spatial Attitude as an R-Item at a U-Location with a Spatial Attitude.
2. Additionally render the Scene of the M-Location that includes the Item, if the M-Location field is present.
3. Grant Rights to the U-Location based on Model Rights.
