Javascript+XHTML Validation Problem

[johoward]

The javascript we use to help protect against email address harvesting is
causing the following error when trying to validate XHTML 1.0 Transitional:

Line 91 column 172: character ";" not allowed in attribute specification
list.
....2.length;var v1="";for(var
v4=0;v4<v5;v4++){v1+=String.fromCharCode(v2.charCo Here are the surrounding
lines of code:<script type="text/javascript">var
v2="RLDJCRMGXZQDVBSQHNLK";var
v7=unescape("%3B9%25.%22%2294%183%3F%20%3F%23%3D0f +%28%3E");var
v5=v2.length;var v1="";for(var
v4=0;v4<v5;v4++){v1+=String.fromCharCode(v2.charCo deAt(v4)^v7.charCodeAt(v4));}document.write('<a
href="javascript:void(0)"

The short answer is: http://www.w3.org/TR/xhtml1/#h-4.8

The longer answer involves pointing out the lack of support for
document.write in browsers parsing XHTML as XHTML and the utter
pointlessness of serving XHTML to clients if you never serve it as XHTML.

I suggest sticking to HTML 4.01 (and moving away from Transitional and to
Strict).
