Transform creates invalid doctype statement

I'm creating xhtml pages from xml using xslt. The problem is that the Transformer is producing a DOCTYPE that is missing the required spaces between the publicID and systemID, so SAXParser operations I'm doing on the output fail.

xsl:output method="html" version="4.01" encoding="ISO-8859-1"

standalone="yes"

indent="yes"

doctype-public="-//W3C//DTD HTML 4.01//EN"

doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"

produces:

!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"

Notice the two adjacent double quotes. That's not legal.

(Please assume all the appropriate angle brackets, I wasn't sure if they'd get through)

Is there any way to coerce this thing to put out a space there?
