Well, that might be a matter of taste - but actually you'll have to 
provide some sort of  coupling between html and the code. I agree that 
it would sometimes be nice to have some sort of compiletime validation 
here, that ensures that for example a template model and the xmlc-class 
used to bind match. But so far nobody came up with a solution to that, 
neither in barracuda nor in any other web-developement framework I know 
(e.g struts, zope).

Your approach still  depends on non-xmlc-managed, html driven and loosely coupled data. I don't see the advantages here. There have been attempts to make the BTable layout controlled by the underlying html - but I never heard of that again. Even if you did it - it won't be less error-prone and complicated that the BTemplate. But maybe you surprise me :)
