Thinking about the organisation IDs more generally, I've seen a lot of donors using CRS channel codes in their data. Some of these are actually quite useful, especially in cases where more precise organisation IDs may be unavailable (due to systems limitations) or not exist (e.g. for public sector organisations). The channel code can also be quite useful as a way of understanding the type of organisation (it is more detailed and sometimes clearer than organisation type).
Given this, I wonder whether it would be useful to allow the CRS channel code and the
ref to both be reporting on the same
<participating-org> element (for implementing organisations)? Otherwise, it is hard to reconcile the two when an organisation is using multiple
<participating-org> and multiple channel codes.
I did a comparison of DFID implementing organisations and transaction/receiver-orgs here which illustrates this issue reasonably well, I think (code half way down this page)
