Re: [docbook-apps] epub generation result has incorrect DocType

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
