Mmmh... you may be right. In the case of structured text, the whole 
document can be contained in a single text node, and thus can be kept 
"as is" from the user request down to the file. Then we need only a 
generator for converting structured text to XML for publishing.

But in that case, I'm not sure we can actually use the 
SourceWritingTransformer since it expects to write an XML document, thus 
containing at least a root node enclosing a text node.

Well, CVS doesn't really care of what's inside a versioned file ;)
