Font Size and XHTML

Couldn't be change the tag font into style attribute? This could be great for using the output on XHTML sites.

It is strange because if I use change font, the editor generate code with Style instead of tag Font Face="x". If I change size the editor generate tag Font Size="x".

Can this be solved?

Oh my GOD!  That's unmanageable!

PS: Anyway the above beheaviour was referred to Firefox last version 2.0.0.3.

I was looking for a very simple text area editor with this only feature:
bold,  color, size. Optionally, italic, underline, the alignement and links. Stop.
BUT, the output code must be XHTML 1.0 strict or 1.1, avoiding the user to destroy the validation of the page.
Instead I find lots of online editor that use stuff like <font size="x">

RTE is one of the few that have only the problem of <font size="x"> while is using Style for any other thing. Anyway... after you answer I tried with IE and that change everything... I got <font face> instead of Style="font-family" i got with FF.... so I must abandon.

Thanks a lot.
