> the {{:hash}} property represents the content hash of node tree rooted at the
> property's parent node.
> the {{:hash}} property is by default not included in the json tree returned
> by the {{getNodes(..)}} method but can be enabled by explicitly specifying it
> in the {{filter}} parameter.
> returning the {{:hash}} property should be optional since it might be a too
> heavy requirement on some MicroKernel implementations. an implementation
> might e.g. choose to include the {{:hash}} property only on certain nodes or
> it might choose to not support it at all.
> if however a {{:hash}} property is returned it has to obey the content hash
> contract, i.e. identical node trees must have identical {{:hash}} values and
> non-identical node trees must have different {{:hash}} values.
