They "could be" but why must they?  

People are happy that we have informal word processors where we
just apply bold when we want it.  And they are happy that there
are systems that separate presentation from markup.

But why should there not be mixed systems: that let you markup with
stylesheets some presentation effects and then override them for
and informal or particular use?

Writing an XSLT stylesheet is a matter of programming. The more
programming involved, the less ability a non-programmer has of
using the mechanism they can control (markup) to vary a document's
presentation according to their eye and taste.
