WebLoadingData sounds like a storage type, I think you want
WebLoadingBehaviorType ?

[Charlie Harrison, 2016/04/06 14:24:51]

Changed to WebLoadingBehaviorFlag.

+    NoLoadingData = 0,
+    DocumentWriteEvaluatorExperiment = 1 << 0,

We prefer having the same prefix for top-level enum names, e.g.

WebLoadingBehaviorNone,
WebLoadingBehaviorDocumentWriteEvaluator,
...


('NoLoadingData' sounds like we have no payload for the loading..)

[Charlie Harrison, 2016/04/06 14:24:51]

Done.
