Hi Lars,
No, this is a long-standing problem. I notice that you
are using epubcheck version 3 to check epub2 files. It is possible that
the new version of epubcheck is more picky. Did your old epubs have the
DOCTYPE?

Thanks Bob. I can confirm, removing
the doctype-public from xhtml-1_1/docbook.xsl does lead to valid
epubs.
<xsl:output method="xml" encoding="UTF-8" indent="no"
doctype-public=""/>
Have this error been introduced in a recent version of the Docbook XSL? I'm
using the same Saxon version which I used last year to create my epub books and
I did not had this error last year.

I'm guessing that you are using Saxon for processing.
This issue was discussed a couple of weeks ago:

Hello,
I'm generating epub from Docbook input and getting during the validation
one error and one warning with regards to the Doctype.
[java] Epubcheck Version 3.0
[java] Validating against EPUB version 2.0
[java] ERROR:
/home/vogella/workspace/docu/de.vogella.publishing/../output/epub/book.epub/OEBPS/content.opf:
Obsolete or irregular DOCTYPE statement. The DOCTYPE can be removed.
[java] WARNING:
/home/vogella/workspace/docu/de.vogella.publishing/../output/epub/book.epub/OEBPS/toc.ncx:
Irregular DOCTYPE: found '-//W3C//DTD XHTML 1.1//EN', expecting '<!DOCTYPE
ncx PUBLIC "-//NISO//DTD ncx 2005-1//EN" "http://www.daisy.org/z3986/2005/ncx-2005-1.dtd">'.
My input looks simular to the XML file listed below.
Any advice how to remove this error? I'm using DocBook XSL 1.77 for the
transformation.
Best regards, Lars
