91441 - Mozilla prints "-->" but there are no errors in code

Status: VERIFIED INVALID

(SeaMonkey :: General, defect)

Description

[Luca Fasolo]

In the page http://test.gnutemberg.org/opere.it.html
or http://test.gnutemberg.org/opere.en.html
after the second <hr> there are the characters "-->" .
I checked the document with Explorer, Netscape 4.6, Amaya
and these characters are not printed (IMO the HTML code is correct)

Tried with nighlty build 2001071704

Comment 6

[Henri Sivonen (:hsivonen)]

The syntax is wrong.

The comment contains the string "--" which isn't allowed.
http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.4

The document contains the Strict doctype declaration. Syntax errors like this
aren't allowed in documents that claim to be Strict. (In the quirks mode the
comment parsing code implements a quirk for this. The string "-->" wouldn't show
up in the quirks mode.)

Resolving as INVALID.

Comment 7

[Christopher Aillon (sabbatical, not receiving bugmail)]

Just to clarify this, the first comment contains:

<td><b>Copyright 1993--1998 Lars Wirzenius</b></td>

And http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.4 states:

White space is not permitted between the markup declaration open delimiter("<!")
and the comment open delimiter ("--"), but is permitted between the comment
close delimiter ("--") and the markup declaration close delimiter (">"). A
common error is to include a string of hyphens ("---") within a comment. Authors
should avoid putting two or more adjacent hyphens inside comments.
