    According to the XSL spec, fo:block elements with span="all" attribute
    can only be _direct children of fo:flow_. Here's the relevant quote
    [7.20.4. "span"]:

    From your FO excerpt, I deduce that your blocks with span="all" are wrapped
    into at least one more fo:block. In such configuration, the span property
    is ignored, and XEP issues the following warning:

      {? 'span' attribute on block ignored because the element is not
       a direct child of a flow}

    Please check your XEP diagnostic output for similar messages,
    to verify if it is indeed the case.

    > Any suggestions as to how enforce the span?

    Move your spanned blocks to the topmost level, making them direct children
    of fo:flow. For example, the following minimal sample works in XEP:

    <fo:root xmlns:fo="">
        <fo:simple-page-master master-name="page">
          <fo:region-body column-count="3" margin="1in"/>
      <fo:page-sequence master-reference="page">
        <fo:flow flow-name="xsl-region-body">
          <fo:block span="all" text-align="center"
                    font-size="300%" font-weight="bold"
          <fo:block text-align="left">
             Text flows in several columns.
             Text flows in several columns.
             Text flows in several columns.
             Text flows in several columns.
