+// FIXME: Probably this should be renamed to CustomElementInvocationQueue

[dominicc (has gone to gerrit), 2013/12/13 05:11:16]

Let's do the renaming in a follow-up changelist.

I think CustomElementInvocation also needs to be renamed. When processing an
unresolved element, nothing of the author's is getting invoked; "invocation" is
too generic.

Here's a proposal:

CustomElementQueue ("Element Queue" is a spec term)
CustomElementQueueEntry
CustomElementResolveStep : CustomElementQueueEntry
CustomElementUpgradeStep : CustomElementQueueEntry
CustomElementCallbackStep : CustomElementQueueEntry

For now this can be:

CustomElementCallbackQueue
CustomElementQueueEntry
CustomElementResolveStep : CustomElementQueueEntry
CustomElementCallbackInvocation : CustomElementQueueEntry
