I can't get colophon to work in RenderX

I get this error message no matter where I put the colophon tag:

C:\Program Files\RenderX\XEP>xep myAnnotatedInterfaceCulture.fo

(document [system-id file:/C:/Program Files/RenderX/XEP/myAnnotatedInterfaceCult

ure.fo]

  (validate

    [error] Element 'fo:page-sequence' cannot be a child of 'fo:flow'. Only bloc

k-level elements are permitted in this context.

    [validation total: 1 error]

Parse error: Invalid XSL FO source 'file:/C:/Program Files/RenderX/XEP/myAnnotat

edInterfaceCulture.fo': 1 error found during validation

So I guess I'll make it a section with a title.

I can't get two columns in the PDF

1/4/09 Update: So far I can get the whole article to be 1 column or two columns, but I can't get the title page to be one column and the body to be two columns. So it doesn't behave as suggested here.

Wikipedia cf DocBook and DITA

Wikipedia has developed as an open community process sets of meta data reminiscent of DocBook's tags. Further, the Wikimedia blog is adding structured features which move it toward DocBook and DITA.
