It would make sense for there to be an indication in the document as to 
its status, conforming or non-conforming, to help the reader. A consumer 
of ODF could specify that it does not read extended-conforming 
documents, that would be clear and reasonable.

I am not sure what you mean by 'user' here. A producer of ODF documents 
could provide an output that is either conforming or 
extended-conforming. For example, if we compare two documents we could 
generate a result that ignored some changes and only listed those that 
were 'conforming'. Similarly an application that could track 
non-conforming changes could generate a conforming output. The reason 
for allowing extended-conforming is to allow development of 
interoperability within a constrained and defined framework.

I would expect that an application that did not understand formatting 
changes, for example, could read a change-tracked document and ignore 
the format changes while at the same time understanding the text 
changes. Some intelligence in the reader may be needed to do this, but 
not too much.
