[whatwg] 9.2.2: replacement characters. How many?

Section 9.2.2 of the current Web Apps 1.0 draft states:

Bytes or sequences of bytes in the original byte stream that could not 
be converted to Unicode characters must be converted to U+FFFD 

I'm concerned about the "or". For example, suppose there are six upper 
halves of a Unicode surrogate pair in a row and no lower halves. Does 
that turn into six replacement characters or one? Both interpretations 
seem possible.

I suppose I prefer six rather than one, but I don't care a great deal as 
  long as this is locked down one way or the other.
