I'm looking at automatically generating some CWL, and I'm trying to work out if the
arguments of a CommandLineTool will always be contiguous, i.e. if you have a file like this:
cwlVersion: v1.0 class: CommandLineTool baseCommand: echo inputs: - id: foo type: string inputBinding: position: 0 - id: bar type: string inputBinding: position: 0 - id: a type: string inputBinding: position: -1 outputs:  arguments: - arg1 - arg2
arg2 will always be immediately adjacent to each other, whether or not there are arguments to either side of them.
As far as I can tell, this is indeed the case – in this example, the command line generated by cwltool is
echo a arg1 arg2 bar foo, but I can't work out from the CWL spec whether this is guaranteed behaviour. Will all spec-compliant CWL runners generate a command line for this example with
