Re: [docbook-apps] Resolving xi:include with xpointer="element()"

    Hi Peter,
    I think the problem now is that the included file's DTD is not being
    resolved properly. xmllint does not automatically treat an attribute named
    "id" as an attribute of type ID, which the element() scheme requires. The
    included file's DOCTYPE must resolve to the DocBook DTD in order for its id
    elements to be treated as type ID.

    Thanks for your help with this. I've just gotten the latest packages
    from Cygwin installed and xmllint will still not resolve my xpointers.
    It gives me this error for each instance of xi:include.

    $ xmllint -xinclude upgrade-excerpt.xml > resolved.xml
    upgrade-excerpt.xml:25: element include: XInclude error : XPointer
    evaluation failed: #element(UpgradePath)
    upgrade-excerpt.xml:25: element include: XInclude error : could not load
    upgrading.xml, and no fallback was found

    XMLMind XXE is very happy with the syntax of it's own xi:include and it
    finds that "upgrading.xml" is available. This xmllint command was
    executed in the directory with "upgrading.xml."

    Does libxml version 20626 sound like the right tool? Here's what Cygwin
    claims to have:

    $ xmllint -version
    xmllint: using libxml version 20626 compiled with: Threads Tree Output
    Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N
    Catalog XPath XPointer XInclude Iconv ISO8859X Unicode Regexps Automata
    Expr Schemas Schematron Modules Debug

    I'm trying to get xom running but have not gotten it set up correctly
    yet.

    Again, my thanks.
