Sentence:  First of all, reading the whole text is the strongest literary convention, but as was implicit in the earlier discussion, it can now mean at least four slightly different things: reading every texton and <WSD>scripton</WSD>, reading every texton, reading every <WSD>scripton</WSD>, and taking every given path through the text (i.e. exhausting the variety of paths). 
Meaning of the word marked with <WSD> tags:  (dynamic text) An unbroken sequence of textons within a hypertext or other dynamic text as it appears to the reader.
