(j3.2006) Does F2015 allow assumed-rank components in derived types?

Ask Bill replied, no.

Assumed rank is only for dummy variables.  Just like assumed shape.  And unlike 
assumed shape, it is really only for interoperation with C.

If we were to add a concept of "deferred rank" we could then have (nondummy) 
pointers and allocatables of deferred rank, just as we do for deferred shape; 
this would include components.

However, that would be pretty useless without a few other things like SELECT 
RANK.  It would be significant work to develop this idea.
