Yes, the prefix for Dominica is J7, but convention allows that to be 
followed by another numeric digit.  Your argument is like saying that 
the prefix for Canada is VE, but that doesn't mean that there can't be a 
numeric digit after the VE (indeed, Canada's callsign structure 
*requires* the next digit be numeric).

In response to your comment that "Can't recall any J7 and some number 
after it call", thae latest master callsign database from K5ZD lists six 
J79s and one J75.  OTOH, there were only three J7s without an additional 
numeric digit: J7DM, J7OJ, and J7R.  Apparently, in Dominica a callsign 
can come either way.

I've heard K3ZO speak on several occasions about how knowledge of how 
callsigns are formatted in the different countries can be a huge 
advantage in a contest.  However, assumption is not necessarily the same 
as knowledge.
