DOCBOOK-APPS: Font size

[Vladimir G Ivanovic <vladimir at acm dot org>]

When I processed my DocBook 3.1 SGML files with DSSSL and OpenJade, I got
10pt PDF output. Now, when I process the same files (modulo minor
changes) as DocBook 4.1.2 XML files with the DocBook XSL stylesheets to
FO, I get 12pt output.

How do I customize DocBook/XSL/whatever to get 10pt output? I tried
creating a local file, "progguide.xsl" with contents:

   <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
		   version="1.0">
   <xsl:import href="file:///usr/share/xsl/docbook/docbook.xsl"/>

     <fo:root font-family="Times Roman"
	      font-size="12pt"
	      text-align="justify">
       <xsl:call-template name="setup.pagemasters"/>
       <xsl:choose>
	 <xsl:when test="$rootid != ''">
	   <xsl:choose>
	     <xsl:when test="count(id($rootid)) = 0">
	       <xsl:message terminate="yes">
		 <xsl:text>ID '</xsl:text>
		 <xsl:value-of select="$rootid"/>
		 <xsl:text>' not found in document.</xsl:text>
	       </xsl:message>
	     </xsl:when>
	     <xsl:otherwise>
	       <xsl:apply-templates select="id($rootid)"/>
	     </xsl:otherwise>
	   </xsl:choose>
	 </xsl:when>
	 <xsl:otherwise>
	   <xsl:apply-templates/>
	 </xsl:otherwise>
       </xsl:choose>

     </fo:root>

   </xsl:stylesheet>

but, BZZZT, nice try, but not even close, which is not surprising since
I haven't a clue.

   $ saxon -w0 -o progguide.fo progguide.xml progguide.xsl
   Error on line 7 column 24 of file:/home/vladimir/aspectj/doc/progGuideDB/progguide.xsl:
     Error reported by XML parser: undeclared name prefix in: fo:root
   Error on line 29 column 6 of file:/home/vladimir/aspectj/doc/progGuideDB/progguide.xsl:
     Error reported by XML parser: undeclared name prefix in: fo:root
   Transformation failed: javax.xml.transform.TransformerException: XML Parsing failed

I checked the docbook and docbook-apps archives, but I didn't find
anything. There was a message from Michael Westbay about tweaking
docbook.xsl (v1.29) to set "fo:root's font-family" to
{$body.font.family}, but nothing about font-size.

So, how *does* one change the default font-size for a DocBook-FO document?

Thanks.
