[whatwg] WF2: data attribute on SELECT

[Sean Hogan]

A few questions:

1. What happens when the data attribute is cleared?  Are all OPTIONs 
removed? Or no change?

2. What happens when the data attribute is set to the value it already 
contains?  Is that a refresh or no change?

3. Is there a way to start out with a SELECT that has hard-coded OPTIONs 
but no @data, set @data to load some OPTIONs (incrementally or 
otherwise) and then reset to the initial hard-coded options.

cheers,
