This is done in system/classes/theme.php in the theme_header() function.
That function calls Stack::get() on the stack of stylesheets, passing a
function (Stack::styles()) as the second argument. Each item in the
stack is processed by the stack::styles() function.
It would take a crafty bit of work to work within the existing code to
allow xhtml output. The current core code could be modified
(particularly the Styack::styles() function) to output xhtml, but Habari
is html-based.
It should be considered in the future that all output should go through
the theme system somehow, so that it might be possible to use a template
for each of the output stack elements. But right now, the task you've
set upon is quite difficult without modifying core files, which is to be
avoided.
