the conmversion is (partly) done in lua so at some point the

   \ref[number][xx]

gets scanned which is more robust in lmtx than in mkiv

normally one does the conversion differently:

\definelabel[XX][numberconversion=R]
\definelabel[YY][XX][numberconversion=A]

\startTEXpage[offset=2em]
     1: \XX[xx]\par 2: \YY[xx]
\stopTEXpage
