nodetype = list
List structure root nodes are nodes assigned the t-lemmas #Idph or #Forn.
The function of these nodes is to assemble separate nodes into a list (structure) . List structure root nodes are nodes that have no counterpart in the surface structure of a sentence; such a node is added into the structure at the tectogrammatical level and is assigned a functor expressing the function of the dependent nodes (as a whole) in a given sentence.
Nodes with the #Idph t-lemma are the roots of structures that have the function of a title (of a book etc.). For more details see Section 8.1.3, "Identification structure".
Nodes with the #Forn t-lemma assemble (separate) members of a foreign-language expression into a list structure. Individual nodes of a foreign-language expression are sisters with respect to each other, they are assigned the FPHR functor (nodetype=fphr; see Section 5, "Nodes representing foreign-language expressions") and their order corresponds to the surface word order (for more details see Section 9, "Foreign-language expressions"). In this respect, the nodes with the #Forn t-lemma differ from the nodes with the #Idph t-lemma: the dependent nodes of the latter form a tree structure.
List structure root nodes have a t-lemma, functor and other attributes. List structure root nodes have no grammatemes.
There are two possible types of nodes dependent on list structure root nodes:
members of the list:
(if the governing node has the #Forn t-lemma:)
nodes with the FPHR functor (nodetype=fphr), which have no daughter nodes.
(if the dominating node has the #Idph lemma:)
a subtree representing a title, whose effective root nodes have the ID functor.
list modifiers: all other nodes, which are not members of the list (the value of the attribute nodetype is usually complex),
Unlike shared modifiers of paratactic structures, these do not modify each member of a list but rather a list as a whole.
