Thanks, hstang. Makes sense.  Before posting my original question above, I had already thought about whether the in-element could be simply meant to bind a context variable to a value (e.g. seam component), as some sort of declarative prerender logic.    But I didn't want to post my wild guess. 

Anyway, if your assumption is true (have not tested it yet), the name of the element ("in") is a misnomer, as there is actually no injection.   Only the value of a context variable is set.

But I don't know whether a better name for this element would be something like "setContextVar", for example.
