[MarkLogic Dev General] uri-is-file for modules in database

[Erik Peterson]

Geert,

Thanks for your suggestion. That was something tried early on but I  
will revisit it. I'd like to avoid using eval if possible for  
performance reasons.

Seems we should be able to do something like: xdmp:uri-is-file(":my- 
modules-db:here.xqy")...
