XSL_FO processor to support <fo:multi-switch>

[swebb]

Hi all,

I'm working with xsl-fo at the moment to create an interactive document. One of the features which I would like to implement is <fo:multi-switch>, <fo:multi-case> and <fo:multi-toggle>. I am using the Apache FOP processor and have discovered that it doesn't support these elements. I researched a few other processors and found that they don't support them either. www.w3.org (http://www.w3.org/TR/xsl/#d0e12855) provide an example of these elements but I can't find any other examples.

Below is the stylesheet which I modified from the w3.org example to include the fo:root but it doesn't output the image or create the toggle (expand, contract) effect that I am looking for, I am assuming it doesn't do this because <fo:multi-switch> etc. is not supported?

I found this site which does a comparison of a few of the fo processors available and the elements they support - http://www.antennahouse.com/xslfo/impl-comparison-fo.htm and none of them include the multi-switch

Any thoughts or recommendations on this are greatly appreciated, thanks for listening.
