The purpose of the token_node_id directive is to keep together in a node
all of the subnodes containing primitive parser matches (such as single
characters, strings or integers) and to create a single node containing the
full matched character sequence as a single string. The token_node_id
directive does not work recursive but works only for a flat subnode
structure not containing sub-subnodes.
Rules OTOH (may) produce arbitrary deep hierarchical subnode structures.
