Compositional node as an organization's factor of compositional text space
Compositional node is a unit of compositional text organization. This unit can actualize more than one compositional variant. Strong position of the text (the title, the beginning and the end of the text), refrains, precedent phenomenon and figures of speech can be qualified as compositional organization's units. Unifying basis of these text units is the principal convergence of compositional text variants considered as capacity. The principal convergence is the cross point of different ways of the compositional text organization. There are the following types of compositional node: polysemic, idiomatic, syntactic and precedent ones.
