    It seems to close everything and then it throws this error. I uploaded
    the whole output to [1]. If I run it withpout the --output option and
    compare the resultng log to the one, that fails, then I cannot find
    compelling differences except, the last lines that differ:

    Not sure if that helps. These last 4 lines (prefixed with the '+' here)
    seem to be the related to the cause of the problem. Is it related to ...

    ... this comment? To be honest, docbook-xsl sets the encoding and
    doctype values via own parameters, that are then given to the
    exslt:document function. So giving the doctype* attributes via
    xsl:output is not necessary (and normally done via parameters), but also
    not wrong, even for chunked output. But is it a bug, that xsltproc fails
    in this case? If not: Should there maybe be a comment (in a LIMITATIONS
    section) in the manpage (and other related documentation) about this
    issue?

    (be careful: the logs are about 1.5 MB)
