[Hdf-forum] "Re-seating" region references for external links?

If I have a multi-process application, one rank of which generates a 
region reference into a dataset for a file open in that rank, but then 
sends that information to a rank managing a different file containing an 
external link to that dataset, is it possible to save that region 
reference in a dataset in the second file such that it "just works" via 
the external link in that second file? If not, is there something I 
could / should be doing instead? Parallel I/O to a single file is not 
really looking like an option in this case due to the possible numbers 
of files involved and the difficulty of managing collective dataset 
extension operations.

Thanks for any help
