Split Table Desperation - again!

[Johannes Graumann <johannes_graumann@web.de>]

Hello,

While the recent modifications to the split table mechanisms provided by
Hans help me out with my most annoying monster table using the XML mapping
code below (see
http://www.idyll.org:8081/JohSite/context/p46-50_split_working.pdf/view for
the typeset table; clearly to much whitespace, but everything is typeset
and page boundaries are honored) and several other -smaller- tables in the
same tome (see
http://www.idyll.org:8081/JohSite/context/p45_unsplit_working.pdf/view for
a typeset example), one medium-sized table that clearly should not be split
gets split none the less (see
http://www.idyll.org:8081/JohSite/context/p162-163_unnecessary_split.pdf/view) ...
and I have no idea why.

Puzzled and helpless, Joh

XML mapping code:

    \defineXMLsave[footer]
  }
  {
    \splitfloat[lines=\XMLop{lines}]
      {
        \expanded{%
          \placetable
            [\XMLpar{table}{location}{}]
            [\XMLpar{table}{label}{unknown}]
            {\select{caption}{\XMLflush{floattitle}
