since you need to distinguish between primary and secondary index entries,
you can best save/flush them, as in:
\defineXMLenvironment [book]
{\starttext}
{\placeindex
\stoptext}
\defineXMLenvironment [indexterm]
{\defineXMLenvironmentsave[primary] \ignorespaces \ignorespaces
\defineXMLenvironmentsave[secondary] \ignorespaces \ignorespaces}
{\doifelseXMLdata{secondary}
{\expanded{\index{\XMLflushdata{primary}+\XMLflushdata{secondary}}}}
{\expanded{\index{\XMLflushdata{primary}}}}}
\enableXMLelements
<book>
So we have primary<indexterm> <primary>animals</primary>
animals </indexterm> as well as secondary<indexterm>
<primary>animals</primary> <secondary>dogs</secondary>
</indexterm> ones, at least in the Czech republic.
</book>
