Sorry if my comments sound like that. The ideas of your proposal are
very good. The general problem we have is timing; it is hard to finish
s.t. new within a few days or even weeks. (Of course the topic is not
new, we had talked about it in the past, but had never thought it through).

IMO you don't need to change the default selection, but you want to say
s.t. about what happens with the selected content, namely that it is not
processed. As for your example below (repeated here)
<its:translateRule its:selector="/img" its:translate="yes"
its:processContents="no"/>
I still don't understand (even with a different default selection): How
should a processor know that the @src attribute at <img> refers to the
external object?
