you can create a master xml file with includes and process the lots in 
one go ... this is quite convenient when you assemble for instance books 
from chapters that are split into sections ... you can make a xml file 
per chapter that includes the sections and then a book file that loads 
them all ... files can have a processing instruction telling what styel 
to load and you can run individual files or assemblies ... all the stuff 
needed to do that is there (and probably also documented someplace)

anyway, you can always save '\lastpage' during a run ... or you can have 
some shared lua file with chapters/pagenumbers that gets updated by the 
current run

all this is workflow dependent but all can be done without too much hassle

(fwiw: we have some cases where for one projects hundreds of xml files 
get merged runtime and then processed ... the overhead is neglectable to 
the run)
