Summary: generated headers broken

Initial Comment:
http://article.gmane.org/gmane.text.docbook.apps/20388

I am having a hard time trying to figure out why the section names in
http://clisp.podval.org/impnotes/mop-overview.html#mop-ov-mo-init
are so broken:

Section 29.3.5.1, Initialization of Section 29.2.1.1, Classess

instead of

Section 29.3.5.1, Initialization of class metaobjects

the original XML text is:

<xref linkend="mop-cl-init-mo"/>

which points to

<section id="mop-cl-init-mo"><title>Initialization of &c-mo;s</title>

where c-mo is defined like this:

<!ENTITY c-mo '<link linkend="mop-mo-classes">class metaobject</link>'>

and

<section id="mop-mo-classes"><title>Classes</title>

what I don't understand is why the text generation for the header is recursive 
and why does it recursively replaces existing text (in this case, "class 
metaobject") with the generated text (in this case, "Section 29.2.1.1, Classes")

this is with the current xsl pages from
rsync -av --port=5873 docbook.xml-doc.org::xsl docbook-xsl

Message:
do you have regression tests?
if you do not, I am scared.
if you do, you might want to add clisp impnotes to them.
thanks.

Message:
I can duplicate the problem using your sample. It seems to be an error in
handling of no.anchor.mode for link, but I haven't pinpointed where.  I
think it was introduced while trying to fix another of your bug reports
regarding using cross references in section titles and then linking to such
section titles.  I need to be careful not to reintroduce the old problem
while fixing it.

ok, let me try again:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
          "./docbook-dtd/docbookx.dtd" [
 <!ENTITY c-mo '<link linkend="mop-mo-classes">class metaobject</link>'>
 ]>
<book><title>b</title>
<chapter><title>c</title>
<section><title>s</title>
<para>see <xref linkend="mop-cl-init-mo"/></para>
</section>
<section id="mop-cl-init-mo"><title>Initialization of &c-mo;s</title>
<para>p</para>
</section>
<section><title>s</title>
<para>&c-mo;</para>
</section>
<section id="mop-mo-classes"><title>Classes</title>
<para>foo</para>
</section>
</chapter>
<index/>
</book>

you would save yourself (and myself) a lot of time if you just get the
clisp sources...

Message:
With the provided test document (which needed fixup in order to be valid),
I get the following error:

 Error: no ID for constraint linkend: mop-mo-classes.
 XRef to nonexistent id: mop-mo-classes

which is not surprising, since there is no element with the ID
"mop-mo-classes".

This seems to be completely unrelated to any "broken headers".

Message:
Please provide a small, complete, valid, self-contained test document that
can be used to reproduce
the error. 

What version of DocBook-XSL does this apply to? Check the value of
<fm:Version> in the VERSION file.
