Greetings,

I am trying to validate two xml files using the modular document technique that Bob Stayton shows in www.sagehill.net.

My version of xmllint: xmllint: using libxml version 20423

File: Caller.xml <?xml version='1.0' encoding='utf-8' ?> <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"

"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" > <book id="XFree86"> <title>XFree86 Documentation (Docbook Version)</title> <xi xmlns:xi="http://www.w3.org/2001/XInclude" href="Called.xml" /> </book>

File: Called.xml

<?xml version="1.0"?> <!DOCTYPE chapter PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"

"http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd" >

<chapter id='Called'> <title> Chapter Title. </title>

<section> <title>Preface</title> <para>Simple paragraph.</para> </section> </chapter>

Command: xmllint --catalogs --noout --xinclude --valid --dtdvalid http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd Caller.xml

Result: Variable $SGML_CATALOG_FILES not set Caller.xml:6: validity error: No declaration for attribute href on element xi <xi xmlns:xi="http://www.w3.org/2001/XInclude" href="Called.xml" /> ^ Caller.xml:6: validity error: No declaration for element xi <xi xmlns:xi="http://www.w3.org/2001/XInclude" href="Called.xml" /> ^ Caller.xml:7: validity error: Element book content doesn't follow the DTD Expecting ((title , subtitle? , titleabbrev?)? , bookinfo? , (dedication | toc | lot | glossary | bibliography | preface | chapter | reference | part | article | appendix | index | setindex | colophon)*), got (title xi ) </book> ^ Element book content doesn't follow the DTD

I don't know if the problem is DocBook or if the problem is xmllint.

Any pointers or suggestions would be welcome.

Thanks
