Talk:CisLunarFreighter/UML case diagrams

I've started an Earth Station series. Earth Station/Alpha sets up two actors, Marge and her 12-year-old big sister. Marge is code for "margin" because she begins on a constraint boundary in the UML Model. In the case diagram, her role is established within the margin at the upper left-hand corner of the 2-dimentional representation. -- CQ 16:18, 25 February 2007 (UTC)
