open new browser window

I have previously been using javascript to open links in new windows of predetermined sizes, scrollbars, etc.
I want to do this, as far as possible, using just html but W3C now tells me that there is no attribute "_target" which seemed the obvious way to go.

Can anyone tell me why W3C doesn't like "_target" and what the acceptable alternative is?

I have a list of 33 places that need to open in a new window when selected, leaving the original window untouched. Ideally I would like to be able to set the size of the new window. but imagine this isn't achievable w/o using javascript.

Any ideas?

target="_blank" ?

This was deprecated for accessibility reasons primarily.

It is consider bad form to open up new windows as it can confuse both sighted but less able people and those using assistive technology.

Cheers Chubbs, that's what I meant to say!
Geoff, more bad form from me I'm afraid. So what do you do when you want your viewer to check out another site or short page, and not lose them from your own site or original page? It seems to be standard issue on loads of sites (including this one!).
I found a way to open link in a new window and otherwise, if the viewer has disabled javascript , the link opens in the existing window...so I'm going to post this thread on the javascript forum to solve another problem that has arisen.
See you there I hope! Thanks

What some sites do is indicate, sometimes in a graphical way, and also in the title attribute that this link opens a page on a different site.

That way the users of assistive technology, etc., knows exactly what is happening.

Oh, and you make sure your site is worth coming back to.
