I agree that it's probably not realistic to assume that such a large
pool of plain text data exists.

This is, I think, the main point here.  This can't be done entirely in
the markup level, which is kind of unfortunate, but I don't believe
that we should be aiming to support every conceivable use case at the
markup level.

Agreed.

I agree with Aharon in that the feature as discussed in the f2f
meeting is overly complex, and I'm not convinced that it brings enough
value in order to be included in this specification.  Therefore I'd
like to support retracting it from the proposal.
