Function walkAttribute

expr/attribute.go:199–223

walkAttribute iterates over the given attribute, its bases and references (if any). It calls the given function giving each attribute as it iterates. It stops if the given attribute is not an object type or there is no more attribute to iterate over or if the iterator function returned an error. It
