gives

9 0 obj
<<  /Type /StructElem /S /H1 /P 8 0 R /K  >>
endobj

It is unclear how to resolve it: removing the StructElem would break the tree. And leaving out the /K probably be invalid. Perhaps a dummy kid?

Leaving out /K is OK according to ISO 32000-1. This entry is marked as optional in ISO 32000-1, Table 323.
