Hi Michael,
I thought about this some more and created a more general solution that does
not require modifying the book template, and handles mixed content in a
book. The book template does xsl:apply-templates on all of its children. I
created one template that matches on the first article of a sequence and
creates a fo:page-sequence for the set of articles. After processing its
content, it applies templates in a new mode to the next element *if* it is
an article. That template just processes its content without creating a
fo:page-sequence, and then processes the next element if it is an article.
This recursive processing stops when the next element is not an article.
You have to use a new mode so that you can turn off the normal processing of
those subsequent articles so they are not processed twice.
<!-- this template selects the first of a sequence of articles and
creates the fo:page-sequence for the sequence -->

Let me know if any of this is unclear.

book
Bob,
I think I will need your help on this. In spite of having used DocBook for
some time now, the stock stylesheets have been most sufficient for my
needs. I haven't yet really learned XSL.
So, I created a customization layer, my-customizations.xsl and copied into
it the template match for d:book from fo/divisions.xsl (ver. 1.78.1)
beginning with <xsl:template match="d:book"> and ending with <xsl:template
match="d:book/d:titleabbrev"></xsl:template>.
Then I copied the d:article template from fo/component.xsl (ver. 1.78.1)
beginning with <xsl:template match="d:article"> through <xsl:template
match="d:article/d:titleabbrev"></xsl:template>.
I then removed the lines <fo:page-sequence hyphenate="{$hyphenate}"
master-reference="{$master-reference}"> through the closing
</fo:page-sequence>.
And then...
Well, I don't know what to do then

Hi Michael,
An XSL-FO output file is structured into a series of fo:page-sequences,
each
with its own designation of a page-master to declare the page specs. The
default processing of article is to put each article in its own
fo:page-sequence. That always forces a page break between articles.
To prevent such page breaks, the XSL template matching on book in
fo/division.xsl would need to be customized. When it encounters a set of
articles, it should start a single fo:page-sequence and apply-templates
to
all the articles inside that sequence. But since fo:page-sequences cannot
be nested, you would also need to customize the template for article in
fo/component.xsl to remove its fo:page-sequence.
