I agree with the idea that namespaces could provide this functionality, 
except that most folks recommend not versioning the namespace. I believe 
you or someone in this thread suggested using the version attribute for 
this function. Well that might work if the parsers actually did something 
with the version attribute. The only mechanism that I can be sure will be 
caught by the parser is to use the namespace with a version to indicate 
that the document conforms to a different version of the standard than 
someone else might be using.
