The serialization context ONE def application (or a whole document's worth)
deserializes through: rooted at the COMPOSITION root so {guid} references in
def data resolve across the whole composed result (cross-reference wiring).
baseUrl: URL-string component fields (e.g. a tracked image's remote object) go
through the EXISTING AssetReference.getOrCreate deserialization — it needs a
source id to resolve document-relative urls against (no new loading path).
