Thanks Ken.

I think the second solution in your Yahoo list answer is the one for my
case, as I am using multiple page-sequences. I created a
page-sequence-master with two alternatives, one for page-position="last" and
for page-position="any". Unfortunately though, I am rendering PDF using FOP
- and FOP seems to have a bug which means that every page is assumed to be
the last page, which messes things up somewhat.

However I don't think there's anything wrong with the approach you describe
- I tried something similar using "first" and "rest" instead of "last" and
"any" and FOP rendered this fine. Also I have seen this bug reported
previously on the fop-dev mailing list. I will follow up on fop-dev to
confirm that this bug still exists.

Assuming the bug is still there, do you have any alternative solutions which
don't use page-position="last" - bearing in mind that I have multiple page

Thanks again,

Coincidentally, this was asked and answered this morning on the XSL-FO 
Yahoo list and I offered two solutions:

Yes, that is the way to do it.

Correct ... the design of XSL will never allow that because citations are 
resolved by the formatter at formatting time long after transformation has 
been completed.  Transformation cannot act on the result of formatting in 
XSL-FO.  The arms-length relationship between transformation and formatting 
burdens the transformation process with providing contingencies from which 
the formatter chooses based on the situation in which it finds itself.

I hope this helps.
