This seems like such an ancient topic, but here it goes...

I have the following:
<xsl:output indent="yes" doctype-public="-//W3C//DTD HTML 4.01//EN"
doctype-system="http://www.w3.org/TR/html4/strict.dtd"/>

The resulting HTML document has a bad content-type meta tag:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

(It is not closed)

I've tried various doctypes and the results seem to be the same.  How
do I solve this?

Also, while on the subject, what doctype do you use, and why?

Karl..
