- real objects, not just JSON-stringified-attributes or so
- shouldn't leak memory
- should also work in non-standard browsers like IE8 or so
I was thinking about doing it with a global array that holds the data and putting the indexes in attributes of the nodes, but that would leak memory because there's still a reference from the array to the data when the nodes aren't in th DOM anymore. It's for a web application, so that could be an issue.
