The default value for alternate is false. It is expected to have several alternate="true" style sheets and a single default style sheet (alternate="false" or no alternate attribute at all). When XXE finds several default style sheets, it simply uses default style sheet declared first. In summary, you need to add alternate="true" to the declaration of the DocBook style sheet bundled with XXE before adding a declaration for your own custom style sheet.
