Hi,

Whilst developing a CSP that potentially sits (directly) above e.g. any 
union or anything with a dummy tlist we observed some problems as the 
set_customscan_references cannot handle any dummy tlists and will give 
invalid varno errors. I was wondering how we can fix this, and I was 
wondering what the reason is that there is actually no callback in the 
csp interface for the set_customscan_references. Can someone maybe 
clarify this for me?

Thanks!

Regards,
Luc
