An informaltable that chokes FOP

["Stephen Taylor" <sjt@5jt.com>]

The attached short article renders perfectly in XEP but breaks FOP. The source of the problem appears to be my customisation layer: with XSLT against just the XSL distribution, the formatters produce identical results.

Or — is the problem with FOP's support for informaltable? If I change the informaltable element to a table element, both FOP and XEP again produce identical results against my customisation layer.

I haven't so far attempted any customisation of tables. Is there something I've written in the customisation layer that affects the informaltable element? Or is this a bug I should report to the FOP project, and if so, in what terms?

• FO for both formatters produced by xsltproc from docbook-xsl-ns-1.74.0
  
• versions.xml validates against docbook-5.0/dtd/docbook.dtd
• FOP reports: java.lang.IllegalStateException: Flow 'xsl-region-body' does not map to the region-body in page-master 'blank'. FOP presently does not support this.
