XML Processing Model

The W3C have posted a Note discussing requirements for an XML Processing Model. This is good news, there’s been a lot of desire to see this work progressing for some time now. Wonder whether XML Pipeline will serve as a possible basis for a specification? It seems to be a good match to the requirements.
It’ll be interesting to see how this ties in with the DSDL work which is essentially defining a validation oriented processing framework. Frustratingly there’s been little updates to the DSDL web site to see how far they’ve progressed. This xmlhack report seems to have the most recent summary of activities. Please update your site DSDL people!
