Could you elaborate on the use case? Why do you use them / want to use them? What are they for?

That certainly is a solid way of approaching things. On Thu, 7 Feb 2013, Randy wrote: > > As far as I'm aware, Data Blocks should be or is part of HTML5.

Right. > It might be useful to mention explicitly in the spec that browsers do > not generally allow non-script to be specified via the src attribute. The spec seems pretty clear about this: # When used to include data blocks (as opposed to scripts), the data must # be embedded inline, the format of the data must be given using the type # attribute, the src attribute must not be specified, and the contents of # the script element must conform to the requirements defined for the # format used.

Implementation-dependent behaviour is, on the whole, just a source of confusion for authors, so I'd rather not do that.

So long as everything is same origin, you can read anything you want via XHR. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
