Hi,

I'm not sure if my message on the regular list got noticed but

     \setuphead[chapter][referenceprefix=+]

doesn't work in LMTX and MkIV.

Below is a fix the LMTX version (I used MkII as reference):

\def\strc_sectioning_set_reference_prefix
   {\ifempty\currentstructurereferenceprefix
      % nothing
\orelse\ifx\currentstructurereferenceprefix\m_strc_references_prefix_yes
-    \global\advance\prefixcounter \plusone % temp here
-    \setupglobalreferenceprefix[\the\prefixcounter]%
+    \ifempty\currentstructurereference
+      \global\advance\prefixcounter \plusone % temp here
+      \setupglobalreferenceprefix[\the\prefixcounter]%
+    \else
+      \setupglobalreferenceprefix[\currentstructurereference]%
+    \fi
\orelse\ifx\currentstructurereferenceprefix\m_strc_references_prefix_nop
      \setupglobalreferenceprefix[]%
    \else
      \setupglobalreferenceprefix[\currentstructurereferenceprefix]%
    \fi
    \glet\currentstructurereferenceprefix\referenceprefix}
