Re: [tdf-discuss] OOXML ECMA-376, transitionnal and strict

Just seen with the System IT team : 

Unzipping every OOXML attachment and checking a tag inside a specific XML file could be done by 
This would be done on the incoming email server. 
We would choose a behaviour depending on the result, wether the file is strict OOXML or 
transitionnal OOXML. 

As we never had this kind of need before, it's costy in matter of ingeneering time. 

If/when you have information about how to dinstinguish transitionnal from strict OOXML, I would be 
glad to hear from it. 

Then I'll ask my direction if we can dig this (and update the thread whatever the answer is). 

Thank you again for your care and your expertise. 

Best Regards.

The question is, how do we enforce the rules with the greatest

Unfortunately, interoperability is strictly related to the user 
behaviour, and should become a topic for students in schools. Users 
should learn how to create interoperable documents, not only related to 
fonts but also to other document elements. 

In my opinion, an automatic reply of the administration ingoing email 
platform would be the best solution. It would reply automatically to 
anyone who sends an email with a transitionnal OOXML attached. This 
email would be written very carefully whith information about IGR v2, 
about the 2 versions of OOXML and about what are the best practices 
to communicate with a french administration (ODF). 

This could educate users, over the very long term (as most users will 
completely ignore the remark). 

Therefore is the following question : What is the easiest way to know 
wether a file is written in strict OOXML or not ? 

I am investigating the issue myself, as I will talk to an audience of 
public administration employees in Italy in two weeks, and I will have 
to cover the topic. 

Or maybe just checking if a single file exists or not would tell us 
if the file is strict or transitionnal ? 

For sure, MS Office 2013 used to have huge problems in handling OOXML 

Microsoft answer on the topic is that I did something wrong as a user, 
because I created some content before saving the OOXML Strict, while MS 
Office defaults to OOXML Transitional when you enter contents (so, you 
cannot save as OOXML Strict a document with contents). 

By the way, this was scrutinized by the UK Cabinet Office.
