XSLT Extensions for JSON Processing

Abstract

XSLT 3.0 contains basic facilities for transforming JSON as well as XML. But looking at actual use cases, it’s clear that some things are a lot harder than they need to be. How could we extend XSLT to make JSON transformations as easy as XML transformations, using the same rule-based tree-walking paradigm? Some of these extensions are already implemented in current Saxon releases, so we are starting to get user feedback.
