Last Call: XProc: An XML Pipeline Language

The XML Processing Model Working Group has published a Last Call Working Draft of XProc: An XML Pipeline Language, a language for describing operations to be performed on XML documents. A pipeline consists of steps. Like pipelines, steps take zero or more XML documents as their inputs and produce zero or more XML documents as their outputs. The inputs of a step come from the web, from the pipeline document, from the inputs to the pipeline itself, or from the outputs of other steps in the pipeline. The outputs from a step are consumed by other steps, are outputs of the pipeline as a whole, or are discarded. Comments are welcome through 02 February.
