Things To Try With Custom Elements

ActionItems.md

1. Moving blur and beforeunload to run asynchronously (custom element callback timing?)
2. Moving mutation events to custom element callback timing
3. Running attributeChanged callbacks for attributes set by the parser and defining the order for that
4. How to work around the compound set of attributes in HTML spec?
5. Experiment with didFinishParsing as timing to address non-determinism.
6. Consider adding childrenChanged callback as a way to guide the authors to never look at the children in the constructor. Merge the callbacks to avoid spamminess? Maybe just one callback per compound operation?
7. LATER: Some option to do hack the parser (void elements, template-like elements). Some thinking needed to ensure forward compatibility.

Where are these being tracked and who is looking at them?
