We have talked about some of this previously, but we should clarify  
the details with the TC.

Preserving xml:ids per se -- both the attribute and its value -- is  
not per se important because of the binding abstraction we use. What  
is critical is that metadata files be preserved (including  
manifest.rdf) and that the binding between xml:ids and IRIs also be  
preserved and maintained.

[for background, it is possible that an implementation will decide to  
rewrite xml:id values at times; that's fine so long as they update  
the binding too; deleting xml:id attributes would be bad though,  
because the bindings would break]

But as Michael pointed out, there are some tricky details. What  
happens if a user deletes content with some metadata fields. Do we  
require the ODF application to preserve the original field metadata?  
I sure hope not.

So the question is how to write this into the spec as precisely as  
possible, and we have tried to do that. But it's definitely something  
the engineers on this committee should pay close attention to, and  
make sure we cover it once it gets to the TC for discussion (very  
soon hopefully!).
