In following my coding style standard, I have two types of commenting for 
each word. The first is the normal stack comment in the standardised style 
used within the standards document. The second is a glossary text entry, 
again in the style of the standards document. I include both types in each 
definitions source code. Such documentation style works with products like 
DocGen to assist in extracting just the names and comments for use in other 
documentation.
