I have questions about the way that the improvements are intended to be 
extensions to the ODF format.

I understand from what is said that improvements are introduced into the ODF 
document in a way that they will be ignored by older implementations and other 
implementations that are unaware of them.  The intention is to map to and from 
.doc in a reliable manner.

 1. How are the extensions introduced such that conforming ODF consumers will 
ignore them properly?  Will users be able to turn off the improvements in order 
to produce conforming ODF documents?

 2. Will ignoring the extensions result in an usable conforming ODF document 
and will round-trip return to the producer of the extensions be tolerable.  
Should there be warning when an user makes changes that rely on the 
improvements in a document that was not produced by an improvement-aware 
implementation?

 3. How are the improvement extensions to the ODF format being made known so 
that other consumers of ODF can support them either partially or completely to 
provide a smoother experience in support of their users and in providing 
interoperability?

b) One of the significant principles of the improvement is to keep
compatibility
http://wiki.services.openoffice.org/wiki/Writer/ToDo/TrackChanges#Design_Principles
with
previous releases of AOO/Symphony in order to ensure the persistent
document. The new formats saved in the improvement will be lost when being
launched into old versions' AOO/Symphony.
