Comment 1

Double hyphens are invalid inside html comments.

Comment 2

[Michael]

Would someone care to explain WHY double hyphens separated from a closing ">" is interpreted as a comment closing token?  Double hyphens should be ignored unless they appear as "-->"  KDE's Konqueror, Opera (Windows and Linux) and IE all ignore double hyphens unless they form a complete comment closing token.  Whay doesn't Mozilla/Firefox??  Unless someone can quote the RFC, FF's HTML parser needs fixed!!!

"A common error is to include a string of hyphens ("---") within a comment"
