4. Tendencies in topic-focus articulation (auxiliary instructions)

The notion of context (see Section 2.1, "Context") is not defined exactly, thus deciding on the tfa value and subsequently evaluating the communicative dynamism can be quite difficult, above all in certain marginal cases. This section contains further guidelines that can be helpful in determining the contextual boundness. They include strong tendencies exhibited by Czech and the influence of four important factors:

All instructions described in this section are auxiliary instructions, the main criterion for assigning the tfa value is always the relationship of a node to its context.
