Ken, David:

Thank you both for your help and discussion. Ken, as I do not have any other
footer information to include in my document, I thought it would be fine to
try your suggestion, and indeed it worked! The only slight issue is that if
the content does run to a second page, I don't necessarily want XYZ to
appear at the bottom of page 2, it should perhaps just go after whatever
text runs onto page 2. This is not definite yet, so I'll stick to this
solution for the moment.

Thanks again,

Haitham.

Thank you, David, for your observations,

Yes, but when there isn't a conflict I personally have no qualms using what 
gives me the end result.

I agree that if the user also has footnotes, this technique can have some 
ambiguity (but in both cases I believe it has only been on the last page).

Oh, I totally agree, but without such a distinction in XSL-FO 1.0, a 
document without footnotes can use footnotes as bottom-floats.

I'm not yet swayed ...

Ah ... good point.

Granted.

No doubt, but I was assuming the user doesn't need footnotes.

This comment addressed an ambiguity in the poster's question regarding 
confusion I had about which pages he was talking about.

content

I discounted that approach because of the fixed extent of the region-after.

As with many posts to these lists where users who don't know the 
capabilities don't know how many of their requirements to reveal in their 
questions, I was trying to propose a solution that handles an arbitrary 
amount of content to be dropped to the bottom of the last page.

Thanks, David, for bringing these issues to light!
