Hello,
Does anybody have an insight into why a table created with the following
mapping rule for XML code does not present it's caption and is not split?
Thanks Joh

first of all, putting a \framed around it makes it unsplittable; best use the framed options that come with the floats 

second, there's a problem in signaling the splitter, which demands a patch

\unprotect

% in core-ntb : we check the flag 

\def\splittblbox#1%
  {\ifinsidesplitfloat
     \donetrue
   \else\ifinsidefloat
     \donefalse
   \else
     \donetrue
   \fi\fi
   \ifdone
     \executeifdefined{splittblbox\tbltblsplitmethod}\splittblboxa{#1}%
   \else
     \notsplittblbox{#1}%
   \fi}

% in page-flt : we add a flag 

\newif\ifinsidesplitfloat % will become chardef

\def\dosplitfloat[#1]#2% nog dubbele refs
  {\ifinsidecolumns    % tzt ook nog figuren splitten
     % not yet supported
   \else
     \bgroup
     \insidefloattrue
     \insidesplitfloattrue

     \resetnumber[\??si]%
     \def\floatcaptionsuffix{\convertednumber[\??si]}%
     \TABLEcaptionheight\@@silines\lineheight % brrr

     \dowithnextbox

        \doloop
          {\setbox2\vsplit\nextbox to \lineheight
           \setbox2\vbox{\unvbox2}
           \ifdim\ht2>\lineheight
             \incrementnumber[\??si]%
             \ifcase\rawnumber[\??si]\or \ifdim\nextboxht=\zeropoint
               \let\floatcaptionsuffix\empty
             \fi \fi
             \bgroup
             #2{\unvbox2}
             \egroup
             \ifdim\nextboxht>\zeropoint
               \page
               \decrementnumber[\floatcaptionnumber]%
             \fi

% beware: you need to set the splitmethod to b (boxed split) 

\starttext

\splitfloat
  {\placetable{test}}
  {\bTABLE[split=repeat,splitmethod=b]
     \dorecurse{100}{\bTR \bTD test \eTD \eTR}
   \eTABLE}

\stoptext

this whole splitting has to be revised (although a two way singaling is not that trivial here)
