This is an interesting remark : it seems preferable for an editor to 
*suggest* rather than to *force* ; thus, the user would be allowed to 
leave a valid state.

I thought that the first <column> could be taken as the model for the 
rest of the <table>, but there is certainly a better strategy to compute 
the boundaries :
-if there is a single <column>,
     min-occurs=0 (or 1 ?)
     max-occurs=unbounded
-if there are several <column>s :
     min-occurs=max(number of <cell>s in the other <column>s)
     max-occurs=min(number of <cell>s in the other <column>s)
So, considering a <column>, the others are "the reference", and you are 
*suggested* to converge, either by deleting or adding <cell>s, until all 
the <column>s have the same number of <cell>s ; however, even if you are 
not suggested to add a new <cell>, you are *allowed* to do so anyway.

This is strange because having min-occurs > max-occurs is possible ; for 
the moment I was reporting this case as an error in the schema, but I 
could reconsider this (maybe by reporting a warning instead), as it's 
only a case where some conditions are not met and can be corrected in 
many actions.

I'm still convinced that defining content models dynamically increases 
significantly the expressiveness of schemata. This is the power of 
Active Schema.
