Javascripts not working under XHTML

[Kerberos]

When I deliver a page as text/html, the javascripts work, but if delivered
as application/xhtml+xml, the javascripts don't work:

function OpenBrWindow(theURL,winName,features, myWidth, myHeight,
isCenter) { //v3.0
if(window.screen)if(isCenter)if(isCenter=="true"){
var myLeft = (screen.width-myWidth)/2;
var myTop = (screen.height-myHeight)/2;
features+=(features!='')?',':'';
features+=',left='+myLeft+',top='+myTop;
}
window.open(theURL,winName,features+((features!='')?',':'')+'width='+myWidth+',height='+myHeight);
}


function Glaydon() {
var uservar = "vendas";
var servidor = "cpedobrasil";
var ext = ".com.br";
document.write("<a href=" + "mail" + "to:" + uservar + "@" + servidor+ ext
+ ">" + uservar + "@" + servidor + ext + "</a>");
}

I'm desperate. I include the javascripts this way:
<script type="text/javascript" src="javascript.js"></script>
Is there a way to have them to work?
I just saw that document.write(); doesn't work under XHTML. Is there a way
to have a similar feature ?
Thanks,

HTML DOMs and XHTML DOMs are quite distinct creatures (both by
specification and by implementation). If you write a script for an HTML
DOM there is quite a good chance that it will not work correctly (if at
all) with an XTHML DOM (and the other way around).

document.write("<a href=" + ...

<snip>

There are currently *no* XHTML DOM implementations that support document
write.

In addition, when scripting XHTML you need to be aware of the use of
namespaces and the case sensitivity of XHTML (as covered in the HTML
level 2 DOM specification from the W3C).

Unfortunately there are people who present XHTML and then script it as
if it was HTML, without mentioning the serious caveats about serving
those (exclusively Appendix C XHTML 1.0) pages as text/html so that the
receiving browser will put a lot of additional effort into interpreting
the pages as tag-soup HTML (Thus creating the HTML DOM that the script
is expecting). That is quite dishonest of them, and misleads others into
believing that they can get away with scripting XHTML as if it was HTML.

In practice the vast majority of the people who understand the situation
would recommend that currently, in any commercial context, HTML should
be authored instead of XHTML whenever client-side scripting is to be
used (and often even when scripting is not to be used).

And I hope there never will be. The idea of *writing tags* (instead of
adding/deleting/moving objects or modifying properties) is hideously
brain-damaged. (And people who want it, or think they "need" it, are
still in the coils of the tagsoup mindset.)
