code: public boolean same(MimeType other) {
  	if (this == other) return true;
  	return getTypeNotNull().equals(other.getTypeNotNull()) && getSubtypeNotNull().equals(other.getSubtypeNotNull());
      }
docs: checks if other is from the same type, just type and subtype are checked, properties (q,mxb,mxt)
  are ignored.
