Hello,

I just joined this list, so please forgive my newbieness. :)

When I recently tried to validate a webpage with the W3C Validator, I
received an error that says:

Line 48, column 38:
                      off his Cute Look&trade;, taken by Libbye. On the
                                        ^
Error: unknown entity "trade"

But, the Character entity reference at
http://www.w3.org/TR/REC-html40/sgml/entities.html#h-24.3.1 shows:

<!ENTITY trade    CDATA "&#8482;" -- trade mark sign, U+2122 ISOnum -->

It does validate if I use &8482;, which is what I ended up doing.

Am I reading the reference incorrectly? Is &trade; valid, or should I use
&#8482; or not use either for valid XHTML? :)

Thanks in advance for your help,
