Hello, I have two questions about dealing with inputs/outputs in the XProc integration API: 1. The APIs are URL-based. Does that mean that the results of running the pipeline must always be saved somewhere (for instance, as temporary documents in /tmp) by the implementation of XProcTransformerInterface? 2. I don't understand how sequence outputs are supported in the API. The XProcInputPortInterface interface uses an array for specifying the URLs for a given input port. Similar to input ports that can take sequences of documents, output ports can also produce sequences - but the XProcOutputPortInterface contains only the getUrl() method. Do I understand it correctly that after the pipeline has finished, the XProc integration code is supposed to store the result data for the output ports to the URL provided by the corresponding getUrl() methods? If so, how does this work with sequences? And what is the method showInSequenceView() meant for?
