What does $content do?  You don't seem to be using it.

It's still not clear to me how much is being repeated that isn't wanted,
but this will process only the last element that has
'outputclass="pagebreak"' [2]:

   <xsl:for-each select="*[contains(@outputclass, 'pagebreak')][last()]">

It's also not clear to me whether there's anything that comes after the
last element that has 'outputclass="pagebreak"'.

That could have been a literal attribute.

I would have thought that the xsl:apply-templates would have gone here,
not before the fo:flow.

Is it the case that all you really need is 'break-after="page"' or
'break-after="odd-page"' [1] on the fo:block for the element that has
'outputclass="pagebreak"'?

I don't understand "prevent <fo:flow flow-name"region.body"> from flowing
in the last node".
