There is a (new) problem typesetting text in chemical structures. Alan Minimal example: \starttext \startchemical \chemical [ONE,Z0] [O] \stopchemical \stoptext ! terminal: (/usr/local/context/beta/tex/texmf-context/metapost/context/base/mp-chem.mpiv)
labtype-10 ! Unknown relation will be considered false. <to be read again> ) chem_text->...XPR3));p:=p.if(labtype(SUFFIX2)>=10) :shifted(0,ypart.center.p)...
chem_z_zero->...(SUFFIX2)((TEXT3),chem_do(origin)) ;endgroup <*> chem_z_zero("\dochemicaltext{O}") ; . system > tex > error on line 4 in file foo.tex: terminal: (/usr/local/context/beta/tex/texmf-context/metapost/context/base/mp-chem.mpiv)
