Yes, it’s possible to do this, but it isn’t the scenario that I’ve heard emphasized in digital publishing discussions, which have tended to focus on retrieval of descriptions (possibly provided by third parties) over a network.

Placing descriptions in separate files within packaged publications would yield a slight performance improvement in the processing of the document, and conserve a modest amount of memory. If the descriptions are included by default in the package together with the primary content, then the privacy concerns don’t apply, unless the reading system is hosted on a server that the user has reason not to trust with information about what her or his needs are.

In any case, I think all that the W3C needs to do is to supply (1) the media query that reflects the user’s “extended description” requirement, and (2) possibly an ARIA role for designating descriptions. Existing HTML elements, including details/summary, figure/figcaption, and other solutions identified in the work of this group can address all of the various use cases of which I am aware. I also support Rich in encouraging implementation of details/summary.
