[Index] The relation between the declarations in template

specializations that 'override' declarations in the base template should use
the 'specializationOf' relation instead of 'specializationOf | overrideOf'.

The indexer relations are meant to be orthogonal, so 'specializationOf' is
better than the combined relation.
