OK.  Then the other suggestions on this thread ought to work.  If there are 
always two periods, then you can use

substring-after(substring-after(@id,'.'),'.')

to get the part after the last dot; to build the entire number for the next 
part, it'll look like (the rather complicated):

concat(
   substring-before(@id,'.'), '.',
   substring-before(substring-after(@id,'.'),'.'), '.',
   number(substring-after(substring-after(@id,'.'),'.'))+1
)

If you don't know how many subparts there will be, then you need to use 
recursive templates to continue stripping as long as there are periods left 
in the string.
