Streaming in XSLT 2.1

The XSL Working Group has been studying how to extend the language to support streaming, that is, the ability to transform source documents into result documents without holding either in memory. This paper describes the current state of the work, as represented in the first Working Draft of XSLT 2.1. This paper discusses a W3C Working Draft which at the time of writing has not been published, and which is therefore not referenced in the paper. When it is published, it will be announced on the home page for the XSL Working Group at http://www.w3.org/Style/XSL/.
