I haven't thought through your example in great detail, but my intuition 
is that it can be handled by deriving not simple types, but complex types 
with simple content.  Complex types with simple content are usually used 
in cases where you want an element like this:

        <e a="1">234</e>

where the element is complex (because it has attributes) but has content 
(in this case the 234) of simple type (perhaps xs:integer).  So, if what 
you're after is:

        <car refid="xxxx">corvette</car>

then that's what you'd want.   In fact, even if what you want is 

        <car>corvette</car>

which has no attributes, you can derive a complex type with simple content 
(perhaps string in this case), that just happens to have no attributes.
