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
