Hi Benoit,

Looks good.  One question/suggestion...

Do you think it is clear to all readers, what is meant by "subsequent 
modification of the user agent's source file using the DOM"?  E.g., some 
readers who haven't participated in the TC might take this to mean 
manipulation of the DOM tree.

How about being very specific:  "Note:  Using DOM 'src' attribute (on the 
WebCGMMetafile interface) to define or redefine the user agent's WebCGM 
source file will cause the 'onload' event to be dispatched."

I just noticed.  In 5.7.10, the event is named 'load', not 'onload' (and 
its companion is 'unload', not 'onunload').  It has always been so.  I 
guess it's a little late to change it's name, right?
