The inconsistent consistencies are driving me crazy

Here’s a simple question: what’s wrong with this code?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
<html xmlns:xf="">
<input type="button" value="X" id="tb_0" onClick="callX(0)" />

Among other things, this is not valid XHTML (as claimed in DOCTYPE) because the onClick attribute should be spelled in all-lowercase (onclick).

Now the trick question: why am I so annoyed by this code? Because it works in IE7, FF2 and FF3 if the server serves HTML to the client and fails only in FF3 if the client performs XSLT transformation using a stylesheet similar to this one:

<?xml version="1.0" encoding="utf-8" ?>

<xsl:output method="html" encoding="utf-8"
  doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system=""/>

<xsl:template match="/">
  <html xmlns:xf="">
  <input type="button" value="X" id="tb_0" onClick="callX(0)" />

The ever-more-crazy implementation of XSLT in Firefox will persuade me to:

  • Stop using client-side XSLT transformations or
  • Stop supporting Firefox and recommend everyone to use IE or Chrome.
