So you propose to add a link fallback feature and always list the local 
document as the first target and the remote as second. But does a fallback 
make sense for non-local documents? How will the processor find out that a 
link is not available?

Meanwhile I think I found a solution: the prefer.internal.olink option allows 
to specify external targets in olinkdb.xml but prefers the local target if 
available. 

The problem with this solution is that I need unique ids within all my 
documents. If I make a mistake with that I'll get incorrect links.

Kind regards,

Gerd
