External Links

There's a wiki article that covers utilizing external links in czml to other json documents or EventSources. Unfortunately it appears that this is still not implemented. I wanted to double check this since I couldn't find any information on it and it seems that it's a bit stale.

This would be a cool feature because as it stands. There appears to be no way to reference objects from two different CZML sources that are loaded independently. The "shared" scope addresses this assuming External Links are eventually added as far as I can. Any thoughts?

Start by reading the linked wiki article about external links in CZML and reviewing the existing handling of independently loaded CZML sources and the "shared" scope. Define how references to other JSON documents or EventSources should work, then verify that objects can be referenced across separate CZML sources.
