Change theme code header from XHTML 1.0 Strict to XHTML 1.0 Transitional?

Hi everybody.

I know this sounds absurd, but I would like to change the DOCTYPE header declaration from XHTML 1.0 Strict into XHTML 1.0 Transitional.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The reason I am asking this is that I would like to be able to use "new windows" links, but XHTML strict does not allow them. Since I use the site for educational purposes, I'd like it to validate under W3C.

Would such a change cause any problems in your opinion?

And, which file should I edit change the DOCTYPE for all the new pages of the blog?

Thanks for your attention
