features or goals with other texts prior to it. Though logically
arguable, intertextuality is best exemplified in criticisms, replies,
paraphrases and comments. Informativity means that a text should carry
at least a minimum semantic load in order to stimulate its recipients
to monitor, manage and change human situations.
Of these seven criteria, two seem prominently text-oriented
(cohesion and coherence); two prominently psychological (intentionality
and acceptability); two prominently social (situationality and
intertextuality), and the last, computational (informativity). Those
criteria are closely inter-related in the sense that 'texthood' is
conditioned by the active and harmonious interplay of these
requirements and/or whether these criteria are upheld. Moreover, "none
of the criteria can be appreciated without considering all four
factors: langauge, mind, society, and processing". (de Beaugrande,
1980, p21).
Standards of textuality, however, are important in so far as text-
actualization is concerned. On the other hand, categorization of
texts/discourses helps not so much as an attempt to compartmentalize
human verbal activity in terms of linguistic science but as a palpable
means of rendering these texts structurally analyzable and,
consequently, understandable. No text-typology, so far, is absolutely
unquestionable, nor unanimously authoritative. Current text-
typologies are the outcome of indefatiguable and ceaseless efforts
made by text-typological theorists in an attempt to establish dividing
lines between various text types. All attempts to set text-typologies,
