- Existent imports are imports that have content that contribute to the processing of a Razor document. Prior to this we had a legacy expectation that code documents had empty markers in them for all of their import locations. This proved troublesome when cross-referencing files that had file paths and were supposed to be existent but weren't in metadata. Now that we have a project engine with a de-coupled import feature we can rely on the import feature for finding all locations of important files and then strip out any non-existent items.
