Example for an XML processing model for ITS

• Three processes are evoked: nrl for namespace sectioning, validation for validation, and xslt for transformations.
• Processes take inputs and outputs, e.g. a source document and rules for namespace sectioning as an input for the nrl process.
• Processes can run in parallel; the results can be merged at the end.
• Where are various possible (emerging) standards for the description of processing models: Pipeline Definition Language, MT Pipeline, or XPL.
