The reference page for <para> lists <xref> as a valid child element [1]. And after assigning the "LFC-to-js2doc" ID to an element in doc-backwards-xform.dbk, the validation error is gone, too. Doesn't that mean the validation error in only caused by the bad ID and thus can be ignored? I'm a bit confused right now...

Yes, the ID errors can be ignored, but this error is not related to that:

Document doc-toolchain.dbk does not validate against
/Users/lou/src/svn/vendor/docbook-xml-4.5/docbookx.dtd

means the file is not valid docbook. A docbook element can only
contain certain other docbook elements, so

<xref linkend="LFC-to-js2doc"/>

in a <para> tag is not legal docbook. That's why you need to escape it.

        A couple of issues:

        The xref part needs to be escaped:
        &lt;xref linkend=&quot;LFC-to-js2doc&quot;/&gt;

        I found similar errors in at least one other file: doc-toolchain.dbk

        You can validate the docbook files like this:

        xmllint -dtdvalid ~/src/svn/vendor/docbook-xml-4.5/docbookx.dtd
        <filename>

        Then look for an error like:

        Document doc-toolchain.dbk does not validate...


    I only see validation errors caused by invalid IDs. This happens
    because the IDs are actually defined in different files, for example:

        $ xmllint -dtdvalid
        ~/src/svn/vendor/docbook-xml-4.5/docbookx.dtd
        doc-backwards-xform.dbk > /dev/null
        IDREF attribute linkend references an unknown ID "LFC-to-js2doc"
        Document doc-backwards-xform.dbk does not validate against
        /home/anba/src/svn/vendor/docbook-xml-4.5/docbookx.dtd


    That ID is defined in doc-toolchain.dbk:

        $ grep "LFC-to-js2doc" doc-toolchain.dbk
        <section id="LFC-to-js2doc">

    Yes I know that, the file was never checked in by Ben. That's why
    I've added this TODO:

            Details:
            doc-toolchain.dbk (Chapter 54. The Documentation Toolchain)
            - id for <view> is still LzView, not lz.view

            doc-backwards-xform.dbk (Chapter 55. The Backwards
        Transformation:
             From Reference Page to Source)
            - correct number of columns in Page Header table
            - left align all examples for better readibility
            - update Lz.swfEmbed to lz.embed.swf
            - update listing in section 4 "Method Details", so it's
        up-to-date again

            docbook-local.dbk (Chapter 56. Local Docbook Style Guide)
            - left align all examples for better readibility
            - fix missing white spaces after <sgmltag>s
            - removed LPP-4033 and LPP-4146 from "Current Gotchas" list,
        both
            issues are resolved

            ecmascript-and-lzx.dbk (Appendix B. ECMAScript)
            - fix listing to use <script> when referring to <script> (!)
            - change all "SWF" references to say "SWF8"
            - fix property access listing to use foo['length'] instead of
            foo.['length']
            - left align all examples for better readibility
            - hide section "Forward references", this works for me
            - todateString() -> toDateString()
            - Error, encodeURIComponent and decodeURIComponent are supported
            - add note for Function.toString()
            - update link to ES-Harmony classes proposal, change wording
        from
        "ECMAScript 4 committee" to "ES-Harmony committee"
