Hi Jirka, Thanks for the information.
It turns out that you were exactly correct. In xhtml-1_1 (which epub2 uses), the files docbook.xsl, maketoc.xsl, and profile-docbook.xsl each contain the following line: <xsl:output method="xml" encoding="UTF-8" indent="no" doctype-public="-//W3C//DTD XHTML 1.1//EN" doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"/> Apparently, this causes all files to have this doctype added, including content.opf and toc.ncx, which use different schemas. When I remove the attributes doctype-public and doctype-system from this line in all three files, the problem goes away and the epub validates correctly against epubcheck. BTW, your message reminded me that I ran into (and fixed) this same problem about a year ago, fixed it, and then forgot about it:-). Update: I just went to sourceforge and found that this problem has been reported, closed, and reopened a couple of times:-). It looks like it may be a case where only some processors exhibit this behavior (possibly just saxon6). It's probably worth checking out with later versions of saxon and xsltproc, but I don't have the time to do that now. I'll try to look at it again in a week or so.
