XProc Error Namespace

1 Introduction

This document describes the names that are defined in the http://www.w3.org/ns/xproc-error namespace at the time of publication. The W3C reserves the right to define additional names in this namespace in the future. Only the XML Processing Model Working Group or its successors may amend this namespace.
