LibXSLT itself is equally stuck at XSLT1 with no upgrade path. Meanwhile, XSLT improved greatly in versions 2 and 3. I’ve used SaxonJ-HE for several projects at work and I have found it to be well maintained. This project would likely prefer SaxonC-HE, I think that would be fine.</span><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">I’m curious if you have ever considered using Saxon instead of LibXSLT and upgrading the filters to make use of the newer language features. I searched the mailing list archives and haven’t found any discussion of this. <div><br></div><div>Compatibility would have to be maintained during development. My suggested course of action would be something like:</div><div>1. Add SaxonC-HE as a dependency</div></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">2. For each filter:</div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><span class="Apple-tab-span" style="white-space: pre;"> </span>1.
