Ah, thanks for clearing that up. None of the reports about the kpdf 
changes bothered to mention that it used a non-standard and incompatible 
annotation method. Pity.

I can understand it, since the xpdf/poppler PDF rendering libraries 
unfortunately provide little or no facility for modifying and writing 
PDF so it's relatively difficult for a library that uses (eg) libpoppler 
to insert annotations and write the PDF out. At least, it was last time 
I looked. In fact, I'd been wondering how the Kpdf folks had built their 
annotation support.

I wouldn't jump into that quite yet. It looks like both the evince and 
kpdf folks have been working on enhancing poppler to support PDF 
annotations. This XML file stuff may just be an interim step, maybe 
intended as a temp file if they're going to use another tool/library to 
insert the annotations.

If you're interested in the problem, you'd probably want to start by 
prodding the kpdf and evince folks to find out what the situation is and 
how you can help.
