NODAL is a data modeling language based on HyTime/SGML Groves.  Data may
be either an atomic type (i.e. int, char, etc.) or a node type.  The three
node types -- MapNode, SequenceNode, StructNode -- are equivalent to
hashes, lists, and structs.  If you're modeling some data in NODAL and you
need one of the latter three data types, then you use the appropriate node
type.    (03)
