You guess correct.
BTW, it just occurred to me, while re-examining the FO you sent, that the
'position' property does not apply to fo:block, so it actually serves no
purpose there.
Specifying the property can almost be seen as wasteful, because it
'overburdens' the property parser. Big word, because it does not matter _that_
much, but "less is more". :-)

Let's see...
The block-container will only be broken if its top/left positioning is
relative, which FOP does not support. Never mind, because that is not what you
want anyway. You would get a page-break, sure enough, but it would still cause
_some_ of the content to be clipped. In fact, what would happen if FOP were to
implement it, is that the block-container would be broken using the full
available page-height, as it does not interact with the absolute-positioned
ones. Then, the generated areas on each page are offset by the specified
amount. Hardly surprising that nobody has ever even asked questions about this
on the user-list (at least AFAIK).
It doesn't look useful --but I'm straying...
Given the above, and assuming that, in the example you sent, you would only
need to see that one block flowing to the next page, you could try using
space-before (instead of "top") and start-indent (instead of "left") to create
the displacement effect.
Something like:
<fo:block-container space-before="8.3cm" start-indent="1cm" width="auto"
height="auto">
<fo:block start-indent="0" font-family="Comic Sans MS,cursive"
font-size="16px" font-weight="700" font-style="normal" text-align="left"
color="rgb(0,0,0)" padding="4px">
<fo:block>TEXT 9</fo:block>
<fo:block> Here is some sample code </fo:block>
<fo:block> Here is some sample code </fo:block>
...
That way, at least that block-container will be split over multiple pages, if
necessary.
Any absolute-positioned content following it, will have its single area on the
last page spanned by the preceding, relative-positioned content. Since it is
likely not known in advance how many lines will end up on that last page,
figuring out the right value for 'top' in such cases would be quite a
challenge. Using 'bottom' displacement may offer a way out, here, but still...
If there is then yet more following relative-positioned content, it becomes
increasingly difficult to manage, since there is no clue as to what the initial
offset should be. You would have to resort to using forced breaks to make it a
bit easier.
It all really depends on how complex the eventual result can become. If it's
only a single block that should flow to the next page, and it is not itself
interrupted/followed by absolute-positioned content, the above would suffice:
use a regular block-container with space-before for the initial displacement on
the first page, or even leave that block-container out entirely, and just
insert the block.
Not sure if this will help, but it's very difficult to say, generically, how
best to address this, without actually having seen some of the more complex
cases.

Andreas
