I can tell you what is generating that error, but I'm not sure how to fix
it. When the DTD resolves with your additional parameter entities, you get
this:
((refentry | xi:include)* | (section | xi:include)* | simplesect*))
and
(refentry | xi:include)+ | (section | xi:include)+ | simplesect+)
The XML standard http://www.w3.org/TR/REC-xml/#sec-element-content says:
"it is an error if the content model allows an element to match more than
one occurrence of an element type in the content model"
An xi:include element can match in either of two places in both of these
parts of the content model, so that generates the deterministic error. So
it looks like you can extend refentry, or section, but not both.
Or manually rewrite the content model for section, but I'm not clear on what
it should be. The section content model is kind of convoluted because it is
designed to prevent mixing of refentry, section, and simplesect children
within the same section.

Subject: [docbook-apps] Content model of section is not determinist
Hi there.
I am having what I believe to be a problem with my DTD which is
causing my documents to fail validation with xmllint.
I am using a DTD that is customised to allow the inclusion of
xi:includes and mathml at certain places within the document. This is
what the customisation (UG.dtd) looks like:
----------------------------------------------------------------------------------------------
<!-- xinclude entities -->
<!ELEMENT xi:include (xi:fallback?) >
<!ATTLIST xi:include
xmlns:xi CDATA #FIXED "http://www.w3.org/2001/XInclude";

accept CDATA #IMPLIED
accept-language CDATA #IMPLIED >
<!ELEMENT xi:fallback ANY>
<!ATTLIST xi:fallback
xmlns:xi CDATA #FIXED "http://www.w3.org/2001/XInclude"; >
<!-- can replace a chapter by an xinclude pointing to a chapter -->
<!ENTITY % local.chapter.class "| xi:include">
<!-- can replace a section by an xinclude pointing to a section -->
<!ENTITY % local.section.class "| xi:include">
<!-- can replace a refentry by an xinclude pointing to a refentry -->
<!ENTITY % local.refentry.class "| xi:include">
<!-- inside chapter or section elements -->
<!--<!ENTITY % local.divcomponent.mix "| xi:include">-->
<!-- inside para, programlisting, literallayout, etc. -->
<!ENTITY % local.para.char.mix "| xi:include">
<!-- inside bookinfo, chapterinfo, etc. -->
<!ENTITY % local.info.class "| xi:include">
<!-- inside equations
<!ENTITY % equation.math "| xi:include">
<!ENTITY % inlineequation.math "| xi:include">
<!ENTITY % informalequation.math "| xi:include">
-->
<!-- MathML entities -->
<!ENTITY % MATHML.prefixed "INCLUDE">
<!ENTITY % MATHML.prefix "mml">
<!ENTITY % equation.content "(alt?,
(graphic+|mediaobject+|xi:include+|mathphrase+|mml:math))">
<!ENTITY % inlineequation.content "(alt?,
(graphic+|inlinemediaobject+|xi:include+|mathphrase+|mml:math))">
<!ENTITY % informalequation.content "(alt?,
(graphic+|informalequation+|xi:include+|mathphrase+|mml:math))">
<!ENTITY % mathml PUBLIC "-//W3C//DTD MathML 2.0//EN"
"http://www.w3.org/TR/MathML2/dtd/mathml2.dtd";>
%mathml;
----------------------------------------------------------------------------------------------
However, when I try to validate a simple document:
----------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE section PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"; [
<!ENTITY % UG SYSTEM "../UG.dtd">
%UG;
]>
<section >
<title>Title</title>
<para>
This is a para.
</para>
</section>
----------------------------------------------------------------------------------------------
using
xmllint --noout --valid --postvalid test.xml
I get the error
----------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------
Does anyone know what's going wrong here? I suspect that I have
incorrectly defined my xi:include within the DTD or something like
that, but I am not sure.
Thank you.
