  Embedding of a Green-Schwarz superbrane into a generic curved target space in
a general covariant way is considered. It is demonstrated explicitely, that the
customary superbrane formulation based on finite-component spinors extends to a
superspaces of restricted curving only, with the General Coordinate
Transformations realized nonlinearly over its orthogonal type subgroups.
Infinite-component, world, spinors and a recently constructed corresponding
Dirac-like equation, enable a possibility of a manifestly covariant generic
curved target space superbrane formulation.
