I already have one XML compressor benchmarked (xml-wrt + ppmonstr/ppmd)

What is xml-wrt? Where can I find it? Is it open source?

Surprisingly, google wasn't much help, nor did I notice any links on
your page for it.

My website was down over the weekend but it's working now.

While it was down I put up a mirror, although I will probably not keep
it as up to date and just link to the original instead.

Anyway it links to XML-WRT and all the other compressors. XML-WRT
improves compression on enwik8 for 14 of 16 compressors I tried (all
except paq8h and uhbc). Source code is included. Rumor is it might be
integrated into a future version of PAQ, replacing WRT, but it will
take some changes to the model, which currently isn't tuned to it.
