I'm not sure I understand what you mean by "values are set after
structure has been validated".

If you mean actually using e.g. a DOM interface to change the tree --
well, if you change the [children] property, why not change the
[attributes] property as well and set the [schema normalized value] of 
the 'xsi:nil' attribute to 'false'?

On the other hand, why isn't making the content optional sufficient
for your needs?
