I don't recommend that you name the Connectors to indicate the names of the connected elements in the way shown in the spec sample. If one changes the name of a connected part then one also has to change the names of (possibly many) connectors, thus reducing the degree of model-driven engineering and increasing error-prone manual maintenance. It also makes the diagrams more cluttered.

I also don't recommend that you name EverySubsystem this way; much better to apply the «subsystem» stereotype and display it. Motto: "trust the stereotype".

TIP: In MagicDraw you can drag the IBD or BDD of a Block onto parts that are typed by that Block to make them the default hyperlink target for that part (so one can just "open the part up" by clicking on it). Together with MagicDraw's diagram icons this makes is easy to make the entire project (and system) navigable.
