Please provide any additional information below, especially a URL or an
HTML file that exhibits the problem.
This is happening on a site I am currently developing for a client. I recently 
put the site up yesterday "as is" so the client could see it. I went to do some 
validation checking today and noticed this problem. Here's the URL: 
http://wemakeitrun.com/accounting2web/
Originally, I had all the javascript that's now in the head section in an 
external file called main.js.
I assume it's breaking validation because it doesn't have the proper <!-- // 
--> or the CDATA tag around it...
