[xep-support] Table test

Thank you for a very interesting example :-). I have doubts about your way
of specifying width for table columns: XEP only supports fixed table layout,
and table column widths are set by <fo:table-column> elements. If you
rewrite your table this way, you get the desired result:

      <fo:table>
        <fo:table-column column-width="15%"/>
        <fo:table-column column-width="15%"/>
        <fo:table-body>
          <fo:table-row>
            <fo:table-cell border="1pt solid black">
              <fo:block>Some text.</fo:block>
            </fo:table-cell>
            <fo:table-cell border="1pt solid black">
              <fo:block>More text.</fo:block>
            </fo:table-cell>
            <fo:table-cell border="1pt solid black">
              <fo:block>More text again.</fo:block>
            </fo:table-cell>
          </fo:table-row>
        </fo:table-body>
      </fo:table>

So, strictly speaking, XEP should ignore widths of single cells at all.
However, it does not: in an attempt to do the first step towards automatic
table layout, XEP tries to adjust widths of columns with no column-width
specified to the width of the topmost cell in this column that has an explicit
@width or @inline-progression-dimension attribute. If you insert a fixed
length instead of a percentage in your original example, it will work :-).
But, strictly speaking, this is abusive. You should not rely upon this kind
of behaviour; please switch to the syntax using fo:table-column/@column-width.

Anyhow, thank you for the valuable feedback. We have inadvertently left this
functionality out (and with an error relative to the interpretation of
percentages);
now we should either document it, or disable at all until a reasonable
implementation of automatic table layout becomes available. Still don't know
which one is preferrable...
