I validated your document in oXygen and I can confirm it is valid. According to the content model of article[1], a title is _optional_. > Then I upgraded this document with db4-upgrade.xsl (Release: $Id: > db4-upgrade.xsl 7660 2008-02-06 13:48:36Z nwalsh $) and I get: > > <!-- Converted by db4-upgrade version 1.0 --> > > <article xmlns=3D"http://docbook.org/ns/docbook" version=3D"5.0" > xml:lang=""> <section><info><title>Hello, ..</title></info> > > <para>world</para> > </section> > </article> > > which is !!! NOT !!! valid ( inserting a article/title element makes it > valid). When I validate your file in oXygen, I get: element "section" not allowed yet; expected element "info", "subtitle", "title" or "titleabbrev" So the best is to insert the missing title element right after article _before_ applying the transformation. According to the RELAX NG schema, an article[2] needs a title. The stylesheet just doesn't know this case which creates an invalid DocBook 5 document. I would consider it a bug. >Is this bug known? Look at [3], maybe there is already one. >Is there a bug tracker? See [3] on Sourceforge. >Patches accepted? Probably yes. :) Tom ---------- [1] http://www.docbook.org/tdg/en/html/article.html [2] http://www.docbook.org/tdg5/en/html/article.html [3] http://sourceforge.net/tracker/?group_id=21935&atid=373747 --------------------------------------------------------------------- To unsubscribe, e-mail: docbook-unsubscr...@lists.oasis-open.org For additional commands, e-mail: docbook-h...@lists.oasis-open.org
