Summary:
QVTr already has queries but they are much less user friendly than e.g. MOFM2T's equivelent for which the first parameter is a hidden self, or indeed QVTo.
Perhaps something closer to Complete OCL would do, allowing def'd attributes or operations.

Discussion
QVTo has contextual helpers.
Syntactically it is trivial for QVTc and QVTo to have contextual queries just by allowing a scoped rather than simple name for the query.
Semantically to avoid duuplicating QVTo AS irregularities we can use the synonym package merges for Complete OCL to make the implementation easy.
