Dims/Paul, Thanks, I have the PXE source and will take a look to see if the bpel-parser + bom would make sense to reuse.
I would like to try and steer this discussion back to my original question on defining a common set of BPEL acceptance tests. Do you think this sounds like a reasonable thing to achieve? I noticed there are BPEL documents located at ( pxe\bpel-scripts\src1.1\good and pxe\bpel-scripts\src\2.0\good ). Do you consider these the PXE acceptance tests? The Sybase donation has BPEL test documents located at ( bpe\bpelTests ). Does it make sense to start by merging these two groups of tests?
