Operations
Signature	Constraints	Documentation
has_path(a_path : String) : Boolean	pre: a_path <> Void	True if the relative path a_path exists at this node.
is_subset_of(other : ARCHETYPE_CONSTRAINT) : Boolean	pre: other <> Void	True if constraints represented by other are narrower than this node.
is_valid() : Boolean		True if this node (and all its sub-nodes) is a valid archetype node for its type. This function should be implemented by each subtype to perform semantic validation of itself, and then call the is_valid function in any subparts, and generate the result appropriately.
path() : String		Path of this node relative to root of archetype.
