Public Member Functions inherited from AttributeBindingBase< PAR >
virtual bool	matchSrc (GenNode const &spec) override
	ensure the given spec is deemed appropriate at that point.
virtual bool	acceptSrc (GenNode const &spec) override
	accept status quo, after verifying the spec from the diff verb
virtual void	skipSrc (GenNode const &refSpec) override
	any reordering or deletion of object fields is prohibited
virtual bool	findSrc (GenNode const &refSpec) override
virtual bool	accept_until (GenNode const &spec) override
	there is no real support for navigating to a 'position', since attribute / data field binding has no notion of ordering.

while, strictly speaking, one can not "insert" fields into a given class definition, this binding can tolerate an INS verb whenever this means to touch a field which is actually known and present in the class definition underlying this binding.

In such a case, we just assign the given value. This implementation leeway is deliberate to support classes with optional / defaultable properties.
