As shown in the diagram above, the data objects no longer include an XSL datastream. Instead, the XSL datastream is located in demo:cmodel and is referenced in the DSINPUTSPEC datastream of demo:sdep. One thing to note: although the XSL datastream is a part of the content model object, its presence isn't actually described by the content model. As it stands, the content model object would itself have to have another content model in order to accomplish this. In this case, however, I don't think it would be 's appropriate to extend the dsCompositeModel schema so such that the dsTypeModel element could take a pid attribute. As it stands, the content model object would itself have to have another content model in order to accomplish this.
Other changes include removing the now-obsolete bDefPID attribute from both the Service Deployment (sDep) Method Map and DSInputSpec schemas. To take advantage of these schema updates, the FORMAT_URIs for DSINPUTSPEC and METHODMAP datastreams should be updated to info:fedora/fedora-system:FedoraDSInputSpec-1.1 and info:fedora/fedora-system:FedoraSDepMethodMap-1.1, respectively.
This work is currently available in the FC-254 development branch and is expected to be included planned for inclusion in the upcoming Fedora 3.1 release.
