Michael Howell (6):
      micro-optimization: use Box slice instead of Vec for Attributes
      Assume that attributes are normally going to be valid
      Use indexes into the array to store id and class, instead of strings
      Make attribute indexes a newtype around u16 instead of usize
      Move attributes limit error into regular limit error
      Move class/id indexes into Attributes
