For compatibility

Section 2.5, "Comments", states that "For compatibility, the string "--" 
(double-hyphen) must not occur within comments."

I figured that this meant the spec authors were not totally happy with this 
restriction, but they added it for SGML compatibility reasons and that "--" 
really was not allowed in comments.  However, both MSXML and Aelfred allow it. 
XP does not.

Who is correct?  Does "for compatibility" mean the parser is not required to 
support this if it is not interested in SGML compatibility?  Is this something 
special about comments?
