Rob thank you for all your replies. The suggestion with iText, if I understood 
correctly, assumes that the front page of every 7th sheet will contain only the 
address. So, I could insert the address pages.  But in reality, the address is 
only a horizontal area of the page. Above and below that area, there will be 
some data, e.g. a front page of a sheet like this could contain the following 
lines:

499
500
501
Address line1
Address line2
Address line3
502
503
504

I thought that it would be a case that other people had met and resolved. I 
will have a deeper look and I will update if I find how to achieve this in FOP  
by only writing xsl:fo.

OK, you've convinced me that you cannot do what you're hoping to accomplish in 
apache FOP.  You cannot have a zero-sized flow on a page far as I know and 
that's what you would need to get the address only on those pages (in some 
static region).

This is not the "trick" I hinted at but might be a better solution anyway.

Make the pdf without worrying about the address page(s).

Use iText to insert the address page(s) as necessary.

I think your case would be quite straight forward:  Open the pdf in iText and 
insert an address page after every 6th page of report data.

We use iText to affect multiple flows.  We have static regions which need a 
flow.  We make those pages in fop with the flow as the region body, then use 
iText to overlay the two pages so it appears that there are two separate two 
columns portions of the page.

Now a printing house incapable of more the six pages or at least doing the 
collating necessary to cover their shortcomings is another very interesting 
question.

The number of "groups of seven" is not known in advance, it depends on the 
input data but the total number of pages will be less than 100. The use case is like this:

We are printing statements (transactional data) and each statement has a 
different number of pages depending on the customer. Each statement is 
enveloped and dispatched. The printing house has only one type of enveloping 
machine that can fit at most 6 sheets into an envelope. When a document is 
larger than 6 sheets, it is splited into envelopes and all of them are send to 
the same address. Each envelope has a 'window' in a predefined area where the 
address is printed. Therefore, on every 7th sheet we should print on an 
absolutely positioned area, the recipient address. Other than this, the flow of 
the content will continue from page to page.

Any XSL:FO suggestion, even if not elegant or not fully resolving this, is 
welcomed !

Re-reading (and quite likely stilll not fully inderstanding) the repeatable-page-master 
reference et al, I'm inclined to agree with Luis.  If you know how many "groups of 
seven" you will be making, I can give you a suggestion from something that is 
working for me.  It amounts to making as many page references as needed.  Not elegant, 
but for me it was critical.

I am afraid that this layout is not possible with the current FOP but I think

way I understand it. In any case, I would like to be proven wrong...

The issue is with the first page of every 7th sheet. Maybe it would help if you 
explain how you intend to flow the content from page to page. When you are on 
page 12th and want to move to page 13th do you let the content flow or do you 
insert a break?

If you insert a break when you get to the first page of every 7th sheet then it 
may be possible. Because then it is like a book where you want each chapter to 
start on a odd page and you can use the blank-or-not-blank trait to achieve 
that. However that assumes you only insert breaks at the end of chapters, which 
in your case would be the end of every 6th sheet. If you want to insert a break 
at the end of every page then it will not work.

OK, then I believe you can define each needed simple-page-master: first, 
second-sixth, seventh and make a page-sequence-master with a 
repeatable-page-master-alternative with a reference to each of the seven pages 
in the sequence. Not sure if the 2-6 can be in a 
conditional-page-master-reference or not.

Hello and thank you for your quick answer!
Concerning your question:
Will you be addressing the static regions of the "seventh pages" differently 
from one another.  In other words does e.g. region-before or page 13 get the same content 
as region-before on page 25?
The answer is no, I will not be addressing them differently.
The regions-before will be the same for pages 13,25th etc.
Cheers.
