   I believe Batik will track modifications to the processing
instructions so you might be able to find the PI (it will be
a previous sibling of the root document element) and remove and
re-insert it (don't append it).

   What I would be tempted to do though would be to send the
CSS through a separate channel and make it the content of a
'style' element and just swap the style element's in the document
(replaceChild...).

    I don't think there is any need.

For the record, the only way i could get this to work was to statically 
create a <defs><style> element with a CDATA section on it and setting 
only the value of the CDATA section dynamically.

Dynamically creating defs, style or CDATA node did not work.

Thanks

    I don't think there is a significant difference (the only
real difference is that it needs to fetch the external stylesheet
vs getting it as part of the SVG Document).

Thanks i'll try this. Is it more efficient perhaps to have an inline 
style element rather than have the CSS elements externalized ?
