I don't know very much about XML and schemas, but is it actually
possible to distinguish an empty text content from a non-existant one
(that would be kind of like "" == NULL)? I mean the text, not the
presence of the node itself.
If empty == non-existant then I don't think you can easily represent
that in a schema. But, as I say, I am not an expert.
Do schemas not allow you to state that text content of a node is optional?
