Hi. I don't believe it is stated anywhere, but it is simply the fact that:

- No feature was removed.
- No feature was altered in an incompatible way.
- All new features are optional (most ODF features are optional).

The TC has an informal understanding to "try really hard" to not break 
backwards compatibility in ODF (by which I mean "ODF 1.0 files are also 
valid ODF 1.1 files but ODF 1.1 files need not be ODF 1.0-valid"). This 
is accomplished by allowing new things in new versions but never 
disallowing something that was allowed in a previous version.

But AFAIK there is no written guarantee that this will always be the 
case. In fact, I suggest you talk to Thomas Zander and ask him if the 
new list specification in the up-coming ODF 1.2 will break backwards 
compatibility with ODF 1.1 in the sense above. I don't know either way, 
I just remember a discussion about lists being under-specified in ODF 
and the TC fixing that in 1.2.

Best,
Daniel.
