This will often work in practice. I consider it extremely distasteful to 
have an application actually decide not just what data *means* but what 
really *is* data and what is just markup convenience. Encoding pretty 
printing as meaningful data in the hopes that the processing code will 
correctly guess which is which is sloppy and will probably be error 
prone. AFAIK, there is no perfect solution, and what we have is no more 
broken than most of the other potential solutions we had available. It is, 
nevertheless, broken.
