Well said! 

Unfortunately, most people tend to exclude any mixed content from
data-oriented applications and the grammar based schema languages
(including RELAX NG) include restrictions that makes it impossible to
restrict the values of the text nodes in mixed content (that's what I
have tried to explain in my RNG book:
http://books.xmlschemata.org/relaxng/relax-CHP-7-SECT-10.html).

It's a chicken/eggs problem: because data heads don't like mixed
content, their toolbox doesn't support it properly and because their
toolbox doesn't support it properly, they don't like mixed content...
