eml-2.0.0beta9 release

[Matt Jones]

Hi Scott,

Sorry I haven't replied -- I've been on vacation last week. Thanks for 
the new document you sent.  We'll be trying to develop it further as 
well and will post here as we discover issues.  I think Dan addressed 
your questions well.

Order of elements does in general matter in XML validation.  We can 
write content models that allow arbitrary order of the elements, but 
that means a more complex schema and makes life more difficult for 
applications that want to utilize EML. Thus, we have tried to specify a 
logical order for the elements and only allow arbitrary order when it is 
really needed.  If there are areas that you think would benefit from a 
relaxation of the order restrictions, please let us know where and why 
and we can discuss a change.

Please do continue to report progress to this list so that we can all 
benefit from the experience and contribute to the discussion of any 
changes in EML that might come form this experience.

Later,

Matt
