Mikołaj Rybiński requested on taverna-users 2011-01-18 the possibility of "xscufllocation" for nested workflows in Scufl2.
The main purpose would be to support externally referenced 'tool' workflows (say on myExperiment) which could be updated on need.
Our suggestion is to do this mainly as an annotation, and to still include the whole definition. Thus the user running the workflow will have the option of using the original or updated definition.
Not sure how to do this in Scufl2 with regards to profiles - as one one need to externally reference both the workflow and the profile - externally referenced workflow bundle?
