Save it?  No ... but place into the FO stream a placeholder replaced by the 
formatter with the page number of the last page, yes.

Create an anchor at the end of your last page sequence, and then do a page 
number citation to that last anchor wherever you need a total count of 
pages.  Personally, I use the generated identifier of the root node for 
this last anchor so as to not interfere with generated identifiers of my 
other hyperlinks:

   Page <page-number/> of <page-number-citation ref-id="generate-id(/)"/>

This handles most of the cases for citing the last page, but does not 
handle an extreme boundary condition that I identified to the working group 
(involving floats), but could not be accommodated in the final version of 
1.0 ... hopefully it will be addressed in the next version of XSLFO.

If you aren't using floats, the above works just fine.

I hope this helps.
