#NIT 3: Section 10, Textual Representation 

Description of problem: This section does not inform the reader why the textual representation description is needed. 

Possible text to be added to section 9 or 10:/ 
    PING and TRACEROUTE report 16-bit SIDS for CRH-16, and 
    32-bit SIDS for CRH-32.  It is recommended that the 
    experimental reports use the text representations 
    described below./
