XSL module in PHP4

Is anyone working on a XSL (specially on a XSLT part) module? I evaluated the market for XSL libraries. The most promissing approaches were XT by James Clark (the author of Expat, currently used in PHP and in XML::Perl and quite some other products, a very good engine) and Xalan by the Apache Group. The problem with XT is that is just available and by the contact I had to J.Clark it looks like he has no idea if he is going to port it to C/C++. The problem with Xalan is that it is just available in a final release for Java and the existing C/C++ version just runs on Win32 (which suckx, to say it directly). I am shure that will change but I do not know if that is a good sign of quality (do not understand me wrong I am no MS hater, just long time experience). I specially think these two products would be good, since: - they are open source - will have or have already a wide base of users - do not use something like the mozilla license - have a high grade of functionality (at least in their Java versions) What will come? Anyone any Ideas? Victor Burwitz
