    I agree that the dimension properties are also not listed for fo:block, but am I
    not again confronted with a half-hearted incorporation of a CSS property in the
    XSL-FO spec? "width" comes from CSS and in CSS it applies also to block-level
    elements (is literally included in the XSL-FO spec), which is in contradiction
    with fo:block. They should also add the exception below the CSS definition of
    "width", because section 5.3.3 doesn't make the exception for blocks in the mapping
    rules of "width".

    By the way, XEP honours the width and inline-progression-dimension properties on
    an fo:block completely. That is why I was convinced it was OK.

    It is time I put my cards on the table. I don't use that design in any of my own
    style sheets, because indeed I have never encountered a case where this would be
    a natural solution. I am, however, also using XSL-FO to implement CSS for the
    print medium and I would like this to be with as few exceptions and restrictions
    as possible. The kind of exception I can live with is complete absence of a
    feature. If possible, I would like to avoid implementing features differently.
    In that context the "auto" value for margin-left and margin-right is causing me
    quite some trouble.
