Hi Dave, what is an iterative stylesheet execution model? I can look into Xalan-C code, but it is time consuming (so I won't look) and I need java xslt processor. I have explored Xalan-J, Saxon and hmm I don't remember the third. The main problem with implementation of incremental one based on any XSLT processor is their internal document model. I can work with DOM style document models only. Xalan has clear architecture, but optimization are everywhere, so there is DTM and special cases. Also Xalan supports so many format, I will only DOM. I've made design of Darwin based on Xalan but special case like two mentioned, breaks my design. Tomas Studva
