Subject: Re: [office] Version Attribute Proposal

I agree with that we make the attribute "office:version" mandatory. It should be helpful for ODF processor to handle ODF documents in the long run. However it seems strange to me that the schema still make it optional while the spec says that it is required for 1.2.

For me, asking that a 1.0 document is valid to 1.2 is not practical.
I don't want to follow what M$ do.

If a 1.0 ODF document had the version, I could 'transform' it into 1.2
(maybe), then work with it.

This is exactly the reason that it should not be optional Michael.
So that a processor knows what to do with a 'different' version to the one
it is expecting.
If no version is present, how can I guess what verison it is?
