No ... these two formatting objects add glyphs to areas on the page, they 
are not representations of abstract numbers for use in arithmetic.

The construct can go in a variable as a result tree fragment to be added to 
the resulting XSL-FO file on demand, but a given page's page number cannot.

My impression is you are missing an important aspect of XSL in that the 
XSLT is "arms length" from the XSL-FO.  Your stylesheet acts on your XML to 
produce XSL-FO, but the XSL-FO engine works on your resulting XSL-FO 
instance only when the instance is completely created.

There is no feedback loop between the on-the-fly formatting interpretation 
and the stylesheet transformation.  Formatting involves supplying the 
engine with contingencies for situations the formatter might find itself 
in, rather than querying the formatter for real-time situations.

I hope this helps.
