Hi Ron,
Apologies for re opening a pretty old post, but I'm sure you would be happy to prove me wrong here!.
Please see this example ,which I think is correct.
The college dean chose Mr.Shankar of the left party, who was associated with the organisation for more than 20 years, to take over all the logistical operations in India.
Here who refers to shankar as the phrase left party modifies shankar.
Now the actual question
is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs
Here again can we not say 100% that which would always refer to the camcorder as the phrase " in the world" modifies digital camcorder.( leaving other grammatical errors for now)?
We can see evidence for this behaviour here ( This is gmat prep / OG problem ) So no copyright issues :)
Emily Dickinson’s letters to Susan Huntington Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumber her letters to anyone else.
here clearly which refers to letters.
