RE: [xml-dev] What is coupling? [Was: 3 XML Design Principles]

Rick Jelliffe makes a pertinent observation offline:

"In my old book, SGML  & XML Cookbook, I have some pages on Yourden and 
Constantine's notions of Cohesion and Coupling. In their software
engineering terms, it is good 
for a system designer to maximise cohesion while minimizing coupling.   They
are Ying and Yang, so any 
discussion of one without the other is likely to be futile."

Comments?
