Hi Brandon, Keith,
You've caught the nuance correctly.
We have a couple of other places in the spec, where things are conditional,
based on if another field is present,
and the syntax we worked with was the best compromise at the time for
expressing this.
We should be able to do better in 3.0, and I'm looking forward personally
to the FileAnalyzed field no longer
being required.
Thanks,
Kate
