xslt - DocBook 5 to PDF transform failing with error: "fo:flow" is missing child elements. Required content model: marker* -

i've inherited doc publishing process takes docbook , builds html , pdf output, using apache fop both. project had been started, never completed. lots of tweaking, i've able of doc sets build (20+), except handful, , fail severe code 1 of these 2 conditions:

"fo:flow" missing kid elements. required content model: marker* "fo:block" not valid kid of "fo:root"

the xml output comes out of docbook , docbook-fop checks out well-formed.

the fop error in 1 book, "endecagloss", example, points end of string:

<fo:flow flow-name="xsl-region-body" start-indent="4pc" end-indent="0pt"/>

here’s log output in case:

[java] severe: javax.xml.transform.transformerexception: file:/scratch/publishing/hudson/jobs/build-main-endeca-documentation/workspace/serverdoc/workingdoc/main/publishing/build-files/../output/fo/gloss/endecagloss/endecagloss-fo.xml:11:10410: "fo:flow" missing kid elements. required content model: marker* (%block;)+ (see position 11:10410) [java] oct 16, 2014 1:30:10 pm org.apache.fop.cli.main startfop

for context, in -fo.xml file it’s @ end of antenna house thing, think trying set header/footer pdf:

does have thought on what’s going on here?

the error message marker* (%block;)+ suggests flow element needs block content while in sample element empty.
