footnote placement in single-file specs in error

[Jeff Johnson]

In the C++ specification, there are some footnotes in the text. They're fine
in the chunked html, but are completely misplaced in the single-file html.
Examples from the 4.1 released spec:

http://refspecs.linuxbase.org/LSB_4.1.0/LSB-CXX-generic/LSB-CXX-generic/cxxclasses.html#DATAREPRESENTATION

the footnoted references are in section 6.1.1.1, in the list below table 6-2.
The footnotes themselves appear at the end of the html page.

In the single-file specification (and also the text specifications, for that
matter), the footnotes appear at the very end of the file. See:

http://refspecs.linuxbase.org/LSB_4.1.0/LSB-CXX-generic/LSB-CXX-generic.html#CLASSES

and you have to scroll all the way to the very end, after the GNU FDL, to see
the notes.

This looks even sillier when the C++ ELF materials are merged into the LSB-Core
spec, as is the case for LSB 5.0.

Note I'm just reporting the one confirment instance. I'm quite sure this has
nothing to do with C++, rather with our layout and usage of the <footnote>
element. I haven't seen other instances of this problem, and in fact a spot
check indicates at least some others come out right.

For example,

http://refspecs.linuxbase.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/usernames.html

is just fine.

I wonder if it's a docbook quirk or bug. The troublesome stanza is footnotes
on items in an <orderedlist>, the above noted "as expected" usage is contained
inside a <table>.
