Re: [docbook-apps] Unsuccessful with Saxon and Fop

[Bob Stayton <bobs at sco dot com>]

I can duplicate this problem with xsltproc and FOP 0.20.5.
The "IPD" in the message is the inline-progression-dimension.

It turns out that this is a bug in the stylesheet.
The revhistory element generates a table that uses the
proportional-column-width() function to set the column
widths.  But the table does not have an overall width
indicator.  Here is what the XSL-FO spec says about it:

-----------------------
The use of the "proportional-column-width()" function is only permitted
when the fixed table layout is used.

If the use of proportional column widths are desired on a table of an
unknown explicit width, the inline-progression-dimension cannot be
specified to be "auto". Instead, the width must be specified as a
percentage. For example, setting table-layout="fixed" and
inline-progression-dimension="100%" would allow proportional column
widths while simultaneously creating a table as wide as possible in the
current context.
-----------------------

I interpret this to mean that a table cannot use
proportional columns if no horizontal dimension is
specified at all.  

If I add width="100%" to the fo:table for revhistory,
there is no error.  Apparently it has to be specified as
some width value.  Should the revhistory table be fixed
at 100% width?
