<A target="_blank"> bug?

Hi,

I have a page with a doctype of HTML 4.01 Strict, containing the tag:
<A target="_blank" href="foo">

According to the HTML4 spec:
http://www.w3.org/TR/1998/REC-html40-19980424/present/frames.html#target-info

and the FAQ:
http://www.htmlhelp.com/faq/html/links.html#new-window

this is the correct syntax to use. However, the validator throws up an 
error:
"Error: there is no attribute "TARGET" for this element (in this HTML 
version)"

The page is not currently online anywhere so I can't provide a URL, but 
it should be fairly easy to reproduce.

Is this a bug in the validator, or is the FAQ & spec wrong?

Thanks,
Ian
