This may be the only good argument for Hungarian naming convention:

 class Person
    def set_name(first, last)
      @strFirst = first
      @strLast = last
      nil
    end

You could use this idea with a different naming convention:

@first_xsd_str

>    def_types :set_name, :first=>'xsd:string', :last=>'xsd:string'

This will eventually get out of sync (Don't Repeat Yourself), but it does
make it easy to carry type information around.
Thus you could have xsd interface as a ruby module you included.
The you  are not using the class as a definition, but simply exposing a
known interface, which is not a repeat yourself issue
but rather a lack of interface compliance if something goes wrong (as if we
care why the program breaks down...).
