    Owen Campbell - 2006-06-13

    I'm having trouble using OrangeVolt with DocBook and wondered if someone could help?

    I'm using the docbook-xsl-1.69 stylesheets and also the docbook test documents. They all work fine when I use Apache Xalan-J 2 as the processor. However, if  I use saxon, I get errors (below).

    I'd like to use saxon because I have other systems which require xslt 2.0 (and these are working fine with OrangeVolt and saxon).

    Many thanks....here's the error...

    Warning: Running an XSLT 1.0 stylesheet with an XSLT 2.0 processor Exception in thread "main" java.lang.AssertionError: Unknown value representation

      could you try to transform your document on commandline using saxon ?

      the issue seems to me a saxon/docbook related bug (docbook applies saxon specific java extensions to the transformation).

      I got around this by using ant tasks to define the processor for individual projects - thanks anyway
