I'm working on a more detailed description to send to the WHATWG list.

The attribute in my earlier mail is just a strawman; whatever the approach, if we end up with a way of saying "if you find that you need this module then you should also make sure to apply this style sheet" then the problem I described exists. I'm just trying to figure out how that should be specced. > In particular, HTTP2 and the TAG's work on package management are better > approaches to grouping network resources than scattering dependency > attributes across a DOM tree. I'm not familiar with the TAG's work (do you have a reference?). HTTP2's new features are somewhat orthogonal to the issue of saying what resources should be activated together, though. (Also, many people won't be using HTTP2, especially the server-cleverness aspects of HTTP2, for a long time, but may still want to be able to declare dependencies.) -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
