Thank you, that's very interesting. The documentation seems to suggest that the binding scope attribute only applies to LDs. Interestingly AMBLIST doesn't seem to display it (N/A is shown).

It seems like there are a few undocumented fields and behaviours being relied upon now. Is there anything being done or are there any plans for IBM to update the doc?
